1. Erosion
The erosion is a very big problem in the agriculture. This problem is especially big where there are slopes, or the surface layer of the soil is very loose. In order to stop the degradation of the soil, thus to be able to use it on the long run and to have good yields, the people have started to come up with multiple solutions. One of the methods has been to reduce runoff from the irrigation, as with it, the top, most fertile layer of the soil is washing away. By using methods where the water falls on the land at a more direct angle, the soil is not washed away. Another method, used at places with steeper slopes, is the terracing. This method is basically creating terrace like flat parts on the slopes, and by doing so, the soil is preserved as it is flat, instead of being on a slope and constantly exposed to runoff and wind.
2. False
The label ''natural'' on the foods is a term that is very often used by the companies, but legally it is not really accepted and regulated. The companies use this term so that they can attract more costumers, leading them to believe that the product doesn't have any artificial additions. This is not true though, as pretty much all foods labeled like this do have artificial additions to them, and since it is legally not regulated as to what should the percentage of organic food be in them, there's not really a standard for it.
3. False
The genetically modified plants are very useful for the elimination of malnutrition among the humans, but on the other hand they are very dangerous for the biodiversity. While these plants will in general not reproduce with the wild ones, the dangers are that these plants are able to easily out-compete the wild ones. The genetic changes in these plants provide them with advantageous traits, such as being larger, producing more seeds, being resilient to harsher weather conditions, which leads to easily take over the wild populations and replace them.

Why does ocean temperature change little from day to night? Marine ice caps keep ocean water from heating up t0o much. Lesser cloudiness over the oceans allows them to soak up more solar energy than land. a. b. Salts in ocean water absorb sunlight during the day and release it at night. d. High heat capacity allows water to gain and release heat without much change in temperature
Answer:
D
Explanation:
Water has a high heat capacity. This means it takes much energy (compared to other elements and compounds) to raise the temperatures of water by a degree. This, therefore, means that during the day, the land becomes hotter faster than the oceans. (The reason for sea breeze during the day). Likewise, during the night it takes much time for the water to lose the heat and drop its temperatures (compared to land – the reason for land breezes at night)
Final answer:
The ocean temperature changes little from day to night primarily due to its high heat capacity. This means it can absorb and release large amounts of heat without a significant change in temperature. The correct option is d. High heat capacity allows water to gain and release heat without much change in temperature.
Explanation:
Water's high heat capacity is a defining characteristic that enables the oceans to moderate Earth's climate. This substantial heat capacity means that a significant amount of energy is required to change the temperature of a volume of water, which is why over 90% of the increased heat content of Earth is absorbed by the oceans. The rest of the energy is distributed amongst ice, land, and the atmosphere. Whereas land surfaces can experience extreme temperature fluctuations due to their lower heat capacity, water absorbs more solar energy and distributes this heat not only through the surface but also at greater depths due to light penetration and water mixing. This distribution, combined with the thermal inertia of such a vast body of water, means that ocean temperatures remain relatively stable, with minimal variation between day and night or even across seasons.
A transitional wave refers to: •• A wave in which particles of water move in circular paths.
•• A wave that forms when the wind blows and has a wavelength of less than 1.73 cm.
•• A type of gravity wave formed by the transfer of wind energy into the water.
• • A wave moving through water deeper than 1/20th but shallower than 1/2 of its wavelength.
Answer:
A wave that forms when the wind blows and has a wavelength of less than 1.73 cm.
Explanation:
A transitional wave refers to a wave that forms when the wind blows and has a wavelength of less than 1.73 cm.
A transitional wave is a type of wave that moves through water that is deeper than 1/20th but shallower than 1/2 of its wavelength. These waves exist in a transitional state between shallow and deep water waves. They can be formed by the action of wind over the water surface.
Explanation:A transitional wave, in a physical context, refers to the wave moving through water that is deeper than 1/20th but shallower than 1/2 of its wavelength. These waves exist in a state between shallow water waves and deep-water waves as the depth conditions change. For example, when a wave moves from the deep sea towards the shore (i.e., a transition from deep water to shallow water), it undergoes changes in its characteristics becoming a transitional wave. It can also be formed by the transfer of wind energy into water.

1. Can a rock that has undergone metamorphism turn into a sedimentary rock? If so, how? If not, why not?
2. By what process does hot molten magma become rock?
3. Carbonate rocks found in the Colorado Rocky Mountains imply what type of deposition environment?
4. In what section(s) of the rock cycle are gemstones formed? Support your answer?
5. The Big Island of Hawaii is 1 Million years old, yet hikers thare almost never step on rock taht is more than 1 thousand years old. Explain.
1. Yes
The sedimentary rocks are the rocks that form the last, and they form from a parent material from the igneous and metamorphic rocks. When we have a metamorphic rock, it means that we have a rock that has formed deeper into the ground, when it has been exposed to higher temperatures and pressure. Over time though, with the geological activities, this metamorphic rock can be pushed on the surface. Once this happens, the metamorphic rock will be exposed to erosion and weathering, thus it will start to get broken apart, and sediments will form from it. If the conditions are right, then those sediments can merge back together, to create a softer, new type of rock, a sedimentary rock.
2. Crystallization
The hot molten magma is the one that forms the igneous rocks, which are the basis for the formation of the other two types of rocks, the metamorphic and sedimentary rocks. In order for the magma to become rock, in needs to cool off, and this happens both on the surface and inside the crust. As the magma cools off, it starts to undergo a process of crystallization, which basically means that it solidifies and crystals are formed. Depending on the location of the crystallization, as well as the speed of it, different types of igneous rocks can be formed.
3. warm and humid
The carbonate rocks are rocks that are very high in carbon content. This type of rocks forms when there has been very large depositions of biomass, mostly by wood, which managed to merge with sediments, and under particular temperature and pressure created a rock. The carbonate rocks can be found exclusively on places that have had warm and humid climate in the past, as the enormous amounts of wooden mass required for this rocks to form can only be found in places like that, as well as the proper conditions that the wooden mass is quickly covered with mud from the outside influences.
4. In all sections of the rock cycle
The gemstones are a group of rocks that can be igneous, metamorphic, or sedimentary. There is a very big variety among them, and that is largely attributed to the fact that these rocks form in the mantle, deep into the crust, close to the surface, and on the surface. It is not just that these rocks have very big variety, but they also differ a lot in which section of the rock cycle do they form, as they can form in pretty much every section of the rock cycle, depending on the type of gemstone. In the gemstone category we have the diamond, quartz, opal, ruby, sapphire etc.
5. Even though the Big Island of Hawaii is one million years old, it is almost impossible to set foot on rocks of that age, but in general the rocks on the surface are not older than 1,000 years. The main reason for this is that the island has an active volcano. Not just that the volcano is active, but it is also a type of volcano that has calm eruptions with enormous amounts of lava flows. The lava flows constantly cover the rocks that already existed, and as it cools of and crystallizes, it forms a new layer of rocks. This process has been going on continuously, so the rocks on the surface tend to be very young because they are formed from the more recent lava flows.
A metamorphic rock can become sedimentary rock through weathering, erosion, and compaction. Magma transforms into rock by cooling and crystallization processes. Carbonate rocks in the Colorado Rockies indicate an ancient marine environment, and gemstones form during igneous and metamorphic stages of the rock cycle. Hawaii's geological youth is due to its ongoing volcanic activity.
Explanation:Yes, a rock that has undergone metamorphism can turn into a sedimentary rock. This transformation occurs when metamorphic rock is exposed to the Earth's surface, where it is broken down through weathering and erosion into small particles. These particles can then be transported, deposited, and compacted over time to form new layers of sedimentary rock.
Magma becomes rock through the process of cooling and crystallization. When hot molten magma cools slowly beneath the Earth's surface, it forms intrusive igneous rock. When it erupts to the surface, it cools rapidly and forms extrusive igneous rock.
The presence of carbonate rocks in the Colorado Rocky Mountains implies a marine environment where these sediments were deposited in ancient seas that once covered the area.
Gemstones can be formed in various sections of the rock cycle, most notably during the formation of igneous and metamorphic rocks due to the high pressures and temperatures needed for gemstone formation.
The Big Island of Hawaii showcases relatively young rocks because it is still geologically active with frequent volcanic eruptions that create new land surfaces, burying older rock layers and continuously refreshing the geological landscape.
Explain 3 reasons why death has a functional purpose from an ecological and systematic point of view.
Answer:
death allows for bacteria and fungus to grow on them, these are called decomposers.
They break down dead animals and plants and return vital nutrients to the soil.
Explanation:
Final answer:
Death has a functional purpose ecologically and systematically by redistributing resources, enhancing inclusive fitness and evolutionary benefits, and influencing societal and cultural evolution.
Explanation:
From an ecological and systematic perspective, death serves a functional purpose for numerous reasons. Here we explore three pivotal ones:
Resource Redistribution: Death allows for the release and redistribution of resources. When an organism dies, its body decomposes, enriching the soil with nutrients that support the growth of plants and provide food for a vast array of organisms. This process supports biodiversity and ecological balance.
Inclusive Fitness and Evolutionary Benefit: Certain species exhibit altruistic behaviors that include the death of one organism for the greater good of its genetic relatives. This concept, known as inclusive fitness, promotes the survival of related individuals, potentially increasing the frequency of shared genes within a population. Such self-sacrificial behavior can be viewed as contributing to the overall fitness of a species.
Societal and Cultural Evolution: Death plays a significant role in human societies by influencing cultural practices, religious beliefs, and social structures. It creates opportunities for individuals to pursue wealth and status, especially evident in rituals like funerals. These practices and beliefs surrounding death can encourage societal cohesion and cultural evolution.
These functional aspects of death in nature demonstrate its integral role in maintaining the balance and progression of life across different levels, from ecological systems to human societies.

The focus of an earthquake is a point: a. on the earth’s surface where the initial release of seismic energy occurs. b. on the earth’s surface where seismic waves are reflected downward. c. within the earth where the initial release of seismic energy occurs. d. within the earth where seismic waves are reflected downward.
Answer:
a. on the earth’s surface where the initial release of seismic energy occurs.
Explanation:
The correct option is A. The focus of an earthquake is a point on the earth’s surface where the initial release of seismic energy occurs.
What are the causes of earthquakes?The tectonic plates move slowly over time, but friction causes them to become impermeable at their edges. When friction on the edge is outweighed by stress, an earthquake occurs, releasing energy in waves that move through the earth's crust and produce the shaking we experience.
The focal point is the location where an earthquake begins within the crust of the Earth. The epicenter is a location on the surface of the Earth that is directly above the focus. Seismic waves radiate outward in all directions from the focus when energy is released.

Anderson's model role if a factor, family, and community
Answer:
thanks
Explanation:
Final answer:
Anderson's ecological onion model emphasizes the importance of family and community actors in effecting change within societal systems, highlighting the significant role they play in individual development and the implementation of successful community programs that address issues like girls' empowerment.
Explanation:
Anderson's Ecological Onion Model and the Role of Family and Community
Anderson's model, often referred to as the ecological or onion model, is a framework for understanding how different societal systems impact individuals, such as girls in Senegal. This model suggests that to effectively promote change, family and community actors must be actively involved. Family and community are seen as critical to a person's development and socialization, influencing their views on religion, work, education, and overall behavior. Moreover, family roles and community involvement are fundamental in programs supporting girls' development, particularly in non-Western contexts where extended family networks are stronger and grandmothers, for example, play a significant role in child-rearing.
Interactionism adds another layer to understanding family dynamics, suggesting that familial roles such as the 'good father' are socially constructed and subject to change over time. Previously, a good father was seen primarily as a financial provider, but now the role includes the emotional and intellectual development of the children. This approach indicates the variability of family roles and their interpretation within societal norms.
Program designers must consider the familial and communal structures when targeting areas such as girls' education, health, and empowerment. Effective community programs employ an asset-based approach, respect cultural roles, and utilize adult education methods that promote critical reflection among community actors rather than coercion. Considering the various decision-making participants within the family and community is crucial for the success of development programs intended to improve the well-being of individuals within these systems.

5. Suppose that every three months, on average, an earthquake occurs in a certain region. Assuming this is a Poisson process, what is the probability that the next earthquake occurs after three but before seven months?
Answer:
0.2709
Explanation:
Given that 1 earthquake occurs in 3 months
∴Number of earthquake that will occur in 1 month = 1 / 3
∴ The waiting time of the earthquake to occur can be shown as
[tex]X\sim exp(\frac{1}{3})[/tex]
And since it is a poisson distribution as mentioned, the waiting time is always exponential.
Now the probability of the next earthquake that will occur after three but before seven months is
[tex]P(3<X<7)=\int_{3}^{7}(\frac{1}{3})e^{-\frac{x}{3}}.dx[/tex]
= [tex]e^{-\frac{3}{3}}-e^{-\frac{7}{3}}[/tex]
= 0.2709
∴ The probability of ht waiting time is 0.2709
Probability calculations for earthquake occurrences over specific time frames.
The probability that the next earthquake occurs within the next three months: Since the average occurrence rate is every three months, this probability is the same as the average rate, which is 1. Therefore, the probability is 1. Given that six months have passed without an earthquake in Papua New Guinea, the probability that the next three months will be free of earthquakes: Since it has been six months without an earthquake, the probability of no earthquake in the next three months would also be 1.
The Earth's magnetic field is generated by which layer? Select one: a. Outer Core b. Mesosphere c. Asthenosphere e. Outer core and Asthenosphere together Which layer(s) from the choices below are defined by physical properties and could be considered a brittle solid? Select one: a. Asthenosphere b. Mesosphere C. Asthenosphere &Mesosphere d. Lithosphere e.Mantle
1. a. Outer Core
The magnetic field of Earth is generated by the forces deep inside our planet. More specifically, it is the convection currents in the outer core layer that are managing to produce the magnetic field. These convection currents are made out of molten rock, and they are caused by the heat that is escaping the inner core and moves outwards toward the outer core. This process is called geodynamo, and its effects have big importance for the Earth and the living organisms on it, especially that the magnetic field of our planet also acts as a protector from the intense sun radiation.
2. d. Lithosphere
The only layer on Earth that can be described as brittle solid is the lithosphere. Unlike the layers that are deeper, the lithosphere is not as hot, nor has high pressure, so the rocks are in solid form, instead of being molten. This layer is also the smallest of all, and it is covering only the uppermost part of the planet. Apart from being the thinnest layer, it is also the layer that is composed of the lightest elements, as during the formation of Earth's layers, the heaviest elements were sinking to the center, while the lighter elements were pushed toward the surface.
Final answer:
The Earth's magnetic field is generated by the Outer Core (Option a). The layer(s) that are defined by physical properties and could be considered a brittle solid is the Lithosphere (Option d).
Explanation:
The magnetic field of Earth is a result of the movements within its liquid metallic outer core. This molten outer core, composed primarily of iron, moves and convects, setting up circulating electric currents which generate the magnetic field. On the other hand, the lithosphere comprises the crust and the rigid uppermost part of the mantle. It exhibits rigid, solid, and brittle characteristics, being easily cracked or broken, unlike the plasticity of the asthenosphere below it, which allows for fluid movement. These layers are crucial in the dynamics of plate tectonics, volcanism, and protection against cosmic radiation through the magnetosphere.
Contrast the internal and external processes shaping Earth’s surface.
Externally, the forces that shape the earth’s surface are weathering and deposition. These are mainly powered by the sun. These forces are responsible for features such as ox-bow lakes and deltas. Internal processes include the convection currents of the mantle – that result in tectonic plate movements- and volcanic eruptions that are responsible for features such as mountains.
Internal processes shaping Earth's surface include plate tectonics and volcanic activities stemming from heat energy within Earth's core. In contrast, external processes, powered mainly by solar energy and gravity, influence the surface through erosion, weathering, and impacts from space projectiles.
Explanation:Internal and external processes play significant roles in shaping Earth's surface. Internal processes are driven by heat energy from the Earth's core and involve movements within the Earth's crust, mantle, and core. They include activities such as plate tectonics, volcanic eruptions, and earthquakes - all of which can cause changes like mountain formation, rift zones, subduction zones, and other geological activity.
External forces, on the other hand, are primarily influenced by solar energy and gravity. They include weather-related events like rainfall, wind, and temperature changes, which cause erosion and weathering of the Earth's surface. An example of an external change is crater formation, which occurs due to the impact of projectiles from space.
Summarily, while internal processes play a role in shaping Earth from within, external processes influence Earth's surface from outside.

Which statement describes the surface layer of permafrost? View Available Hint(s) A) The surface layer of permafrost is called a pingo. B) The surface layer of permafrost thaws in summer. C) The surface layer of permafrost thaws to a greater depth at higher latitudes.D) The surface layer of permafrost thaws in winter. E)The surface layer of permafrost only thaws in areas called taliks
Answer:
B) The surface layer of permafrost thaws in summer.
Explanation:
Permafrost is frozen ground or frozen soil. It is a landform in which the ground remains frozen for over a long period of time usually more than two years. Permafrosts are usually found in high latitude regions. For a permafrost to form, the temperature must remain considerably below freezing point.
The surface layer of a permafrost is bounded by the permafrost table and below it lies the active layer. During summer when temperature rises above freezing point, this layer thaws. In winter times, the surface layer remains frozen.

The Grand Canyon was primarily formed by water erosion while Valles Marineris was shaped by tectonic activity, with wind and possibly water from springs playing a role in later erosional processes. Valles Marineris is also much longer and deeper than the Grand Canyon and is near large Martian volcanoes. Unlike the Grand Canyon, Valles Marineris lacks extensive stratigraphic rock exposure.
The Grand Canyon and Valles Marineris are both massive canyons, yet they exhibit significant differences. The Grand Canyon, located on Earth, was formed over time primarily by the erosive forces of water, specifically the Colorado River. On the other hand, Valles Marineris, situated on Mars, was primarily formed due to tectonic activity, with subsequent modifications by erosion from wind and possibly water from seeping springs.
The dimensions of both canyons also vary greatly. Valles Marineris is roughly 3000 kilometers long and 8 kilometers deep, making it significantly longer and deeper than the Grand Canyon, which is around 446 kilometers long and just over 1.8 kilometers deep at its maximum. Moreover, Valles Marineris is wider and has large volcanoes located near it in the Tharsis region, contributing to its formation.
The stratigraphy of the Grand Canyon showcases a rich tapestry of sedimentary, igneous, and metamorphic rocks, which are visible in its towering walls and provide a window into Earth's geological history. This is a contrast to Valles Marineris, which does not have a similar stratigraphic exposure due to its different genesis and erosional processes.

The answer is c. on the earth’s surface directly above the initial release of seismic energy.
The definition of an epicentre: the point on the earth's surface directly above the origin of an earthquake (Cambridge Dictionary)
In Geology, we said that it is directly above the focus, which is the initial release of seismic energy mentioned in the above sentence.
As the other options do not have the correct location (e.g. within the Earth's surface, beneath the focus).
Therefore, the answer is c. on the earth’s surface directly above the initial release of seismic energy.
Hope it helps!
C). on the earth’s surface directly above the initial release of seismic energy
Explanation:The reason why "C). on the earth’s surface directly above the initial release of seismic energy" would be the correct answer is because this best describes what the epicenter of an earthquake is.
The epicenter is a place on the surface of the earth where it is directly on top of the location where the seismic energy was released. That is the reason why it's called the epicenter, due to the fact that it is directly in the center of the energy.
The places that are on or very near to the epicenter are the ones that are going to be the most impacted, since they're near or right on top of the seismic energy. That's why places near the or at the epicenter tend to experience a lot of damages and experience even greater shaking of the ground.
Whenever you see news about earthquakes, they always mention the epicenter. They mention the epicenter to the viewers so that they know where the earthquake's central point is.

Movement within a glacier is plastic and __________:
a)Fastest in the middle
b)Fastest at the base
c)Fastest at the top
d) Consistent throughout
e) None of the above
Answer:
c) Fastest at the top
Explanation:
The glacier is a large mass of ice, moving slowly down a slope as a compact unit. While in general it can be said that the whole glacier moves as one, not all parts of it move with the same speed. The bottom part of the glacier is moving the slowest, which is a result of the friction between the ice and rocks at the valley and walls. The central part tends to move slightly faster as it is avoiding the friction with the rocks, while the top part tends to be the fastest as it has the least pressure on it, so its movement is the easiest.
he total number of species living in a particular area is referred to as its O biosphere O biome O biotic O biodiversity
Answer:
The total number of species living in a particular area is referred to as its Biodiversity .
Explanation:
Biodiversity -
Biodiversity is defined as the variability and the variety of life existing on the planet Earth . Biodiversity measures the variation in the species , genetics and the ecology of the Planet . In the terrestrial level , the biodiversity is greater near the equator , due to warmer climate and higher level in production .
The biodiversity is not uniformly distributed on the planet , and is basically richer in the tropical region . Less than 10 percent of the Earth's surface is covered by the tropical forest ecosystems and contains around 90 percent of the world's species .
The diversity of marine life is higher near the Western pacific and in the mid latitude band , where the sea surface temperature is highest .
Why are metamorphic rocks so limited in their distribution at the Earth s surface?
Answer: Metamorphic rocks are formed by processes that take place in the depths of the Earth
Explanation: Metamorphic rocks are found in the depths of the Earth because they occur during the processes that take place there. This means that all types of rocks are not evenly distributed due to the processes they occur, so that some rocks, such as sediment, are more present on the surface and easier to find. Metamorphic rocks can reach and be found on the surface due to tectonic movements that push the rocks up. But still, these layers of metamorphic rocks that reach the surface are below some layers of other rocks. In order to find these metamorphic rocks on the surface, wind and water play an important role in the washing of the surface layers of rocks over the centuries, and thus make easier to find metamorphic rocks.
Why has only a small portion of the ocean bottom been mapped?
because the bottom of the ocean is basically unreachable without the right equipment.
Final answer:
The ocean bottom has only been minimally mapped because of the high pressure, dark, and cold conditions requiring special technology, and due to the limitations and low resolution of historical and current mapping techniques like ship-based echo sounders and satellite altimetry.
Explanation:
Only a small portion of the ocean bottom has been mapped due to the challenging conditions and limitations of mapping technology. The deep ocean poses significant challenges such as high pressure, total darkness, and extreme cold, which require specialized vehicles for exploration. Historical methods such as weighted lines for depth measurement were very slow, while modern techniques like satellite altimetry and ship-based echo sounders have improved the situation. Satellite altimetry measures sea surface height, which varies due to underwater features, to infer the ocean's topography. However, ship-based echo sounders have poor resolution in regions seldom visited by ships. The development of technology for studying oceanic bathymetry is ongoing, and vast areas remain unexplored.
Human beings have dramatically altered the flux rate of nitrogen from ________. from soils to the atmosphere proteins to inorganic ions in soils producers to consumers through increased wildfires oceans to soils the atmosphere to various pools on the earth's surface
Answer:
The atmosphere to various pools on the earth's surface
Explanation:
Answer:
Human beings have dramatically altered the flux rate of nitrogen from the biosphere.
Explanation:
Human beings have greatly altered the nitrogen cycle or flow of nitrogen within the biosphere which consists of every place on Earth where living things exist: the land, water, and air. The major cause of this great alteration has been the improper disposal of organic matter, and combustion of fossil fuels which have polluted soils, air, oceans and other water bodies with nitric oxides, elements, and ions that lead to the formation of acid rain and smog, amongst other dangerous by-products.
Express the answer in scientific notation. What is the pressure, in N/m2, at a depth of 50 km in the continental crust?
The pressure is _____× 10 ?N m2 .
Answer:
1.422[tex] \times 10^9[/tex] N/m²
Explanation:
pressure (P) = ρ g h
where ρ= density of continental crust
g= acceleration due to gravity
h is the depth given
density of continental crust is equal to 2.9 g/cm³
= [tex]\frac{2.9\times 10^{-3}}{10^{-6} } =2.9\times 10^3 kg/m^3[/tex]
g=9.81 m/s²
height = 50,000 m
now,
pressure (P) = ρ g h
pressure (P) =[tex]2.9\times 10^3\times 9.81\times 50000[/tex]
=1.422[tex] \times 10^9[/tex] N/m²
Which social justice philosopher(s) influenced the Framers of the United States Constitution?
Answer:
The social justice philosopher that influenced the Framers of the United States Constitution was John Locke.
Explanation:
The Declaration of Independence of the United States of America is an intellectual document that transcends the local revolutionary epic to become a global goal of spiritual well-being for humanity. The document includes words and phrases of profound literary beauty and love of country, justice, freedom and God.
Several intellectual sources inspired American patriots in the creation of the American State, including English constitutional law: the Magna Carta (1215), the postulates of the Assembly of representatives in Jamestown in 1619 and the English Bill of Rights of 1689. Also influential were the writings of John Locke: "Letter on tolerance" (1689) and "Two Treaties on Civil Government" (1689).
Which planet type tends to have few or no satellites?
a- Jovian
b- Terrestrial
c- Kuiper Belt Object
d- Asteroid
Answer:
Terrestrial planets
Explanation:
There are two types of planets:
The inner planets or terrestrial planetsThe outer planets or Jovian planets.The outer planets are gas giants and are made of huge mounds of gases. These planets are Jupiter, Neptune, Uranus and Saturn. They all have satellites revolving round them.
The terrestrial planets are small rock masses. They are mercury, venus, earth and mars. Earth has one satellites and Mars has two satellites.
The asteroid belt seperates the Jovian and terrestrial planets. Beyond the Jovian planets lies the Kuiper Belt Objects or KBOs.
Terrestrial planets, including Mercury, Venus, Earth, and Mars, tend to have few or no satellites. Jovian planets, on the other hand, typically have numerous satellites.
Explanation:The type of planet that tends to have few or no satellites are terrestrial planets. These include the planets closest to the sun in our solar system: Mercury, Venus, Earth, and Mars. While Earth and Mars do have moon(s), Mercury and Venus do not have any at all. Terrestrial planets are contrasted with Jovian planets, or gas giants, which typically have numerous satellites. The Kuiper Belt Objects and asteroids also have few or no satellites, but they are not classified as planets.
