Answer:
The Earth rotation
Explanation:
The Earth rotates in its own axes, that is the reason why it can be observed the Sun and some other starts with the naked area. And apparently all the sky rotates, but actually is the planet the one that is constantly moving.
If the sun is close to Earth, so the light hours during the day are longer, and the visible of sun and stars is no so common.
When the sun is apart to the Earth, so the day hours are smaller, and the probability to observe the sun and the stars at the same time increases.

One way to reduce uncertainty is to increase the number of specific and general environmental forces that are interconnected. Because, when forces begin to interact, the environment becomes more predictable.True / False.
Answer:
False
Explanation:
The environment is dynamic whole understanding it imparts is quite essential as to reduce the uncertainties one does not need to increase the flow of general environment and specific forces. This may create a reverse loop in the system and create hindrances in the environmental settings. As the environment is likely to create opportunities for the growth and development of man and his surroundings. Because if one creates a positive change does not necessarily mean that the change may be positive such as a rise in temperature in summer or the reaction of the body etc. Taking the example of climate change that is the biggest system on earth is due to the man's impact on earth which has reacted to him.Which of the arrows on the climate map above is pointing to the Sahel, the semiarid region bordering the Sahara Desert? A. One (1) B. Two (2) C. Three (3) D. Four (4)
The Sahel is a region in Africa that is located along the southern part of Northern Africa. This region is a natural transitional zone between the deserts on the north and the savanna and tropical forests on the south. The Sahel stretches roughly in an east-west direction, from the shores of the Red Sea to the shores of the Atlantic Ocean.
The climate in this area is semi-arid. The temperatures are hot all year round, the precipitation levels low, though higher than the desert, and it is relatively windy. The landscape is rocky and the vegetation that dominates is of steppe type.
The countries through which the Sahel passes are Senegal, Mauritania, Mali, Burkina Faso, Algeria, Niger, Nigeria, Cameroon, C.A.R., Chad, Sudan, South Sudan, Eritrea, and Ethiopia. These countries are also included in a project for making a forest band in the Sahel so that the desertification is prevented and fought back.
The arrow that is showing the Sahel which borders the Sahara Desert is D. Four (4).
Where is the Sahel?The Sahel is a region in Africa that is just below the Sahara. While it is not as dry as the Sahara Desert, it is quite dry.

The puzzle-like fit of the continents, similarity of rock types across continents, and glacial evidence all were pieces of evidence supporting Wegener's hypothesis of continental drift. What was another piece of supporting evidence?
Answer:
Wegener gave many evidence to the theory of plate tectonics another piece of evidence was the finding of fossils of reptiles in oceans and glossiperious fauna and the similarity of glaciers in all continents
Explanation:
Alfred Wegener is supposed to believe that the supercontinent named Pangaea consisting of northern continents and the southern continent i.e Gondwanaland consisting of southern continents were once the same. Thus he gave evidence in the shape of puzzle-like fit of the continents as similarity of rocks found in the continent's of Africa and South America, as they were one earlier. Further, he gave the supporting pieces of evidence as the glacier landmasses distributed were the same part earlier drifted away from the larger continent of Greenland. The supporting evidence the put forth was the polar wandering forces that he called the flight from poles and drift under the impact of moons gravity and another evidence was the thin sheets or plate moved away due to the wind.Another key evidence for Wegener's hypothesis of continental drift was the similarity of fossils found in different continents, which suggested these continents were once joined.
Explanation:Wegener proposed that the similarities between fossils found only in South America and Africa indicated that these two continents were joined at one time. This idea was part of his larger argument that the continents were once connected in a supercontinent he called Pangaea. He supported his claim by pointing out the resemblances among living animal species on different continents, and asserted that these similarities could best be explained if the continents were once connected.
However, Wegener's idea was initially met with resistance due to a lack of a clear mechanism. The discovery and understanding of plate tectonics years later provided this missing piece, ultimately confirming Wegener's hypothesis and establishing it as a central viewpoint in our understanding of the Earth's dynamic nature.

What is the branch of the study of names, and which studies place names?
A. Toponymy
B. Topography
C. Tapestry
D. Totalitarianism
Answer: toponymy
Explanation:
Toponymy is itself a branch of onomastics, the study of names of all kinds. Toponymy is distinct from, though often confused with etymology, which is the study of the origins of words. A toponymist is one who studies toponymy.
Answer:
A. Toponymy
Explanation:
The branch of knowledge that studies the names of places is called as the toponymy and is thus focuses in the origin of the names and the existence and this word itself derived from the ancient greek work, as topo means names and thus is study of all the branches of the places also referred as the toponomastics, and is general is the names of a place or an entity.To test Copernicus’s model, Tycho took meticulous measurements of the positions of the planets, and he hired Kepler to interpret the data. Kepler found that the geocentric model did not accurately predict the planets’ positions, but neither did Copernicus’s heliocentric model. He found that Copernicus’s insistence that the planets’ orbits were perfectly circular was the problem. If the orbits were instead ellipses, then the heliocentric model would have been able to very accurately predict the positions of the planets. This is known as Kepler’s first law of planetary motion.
A. Elliptical orbits cause a planet to sometimes be closer to and sometimes farther away from the Sun.
B. The Sun is located at one focus of a planet’s elliptical orbit, and the planet is located at the other focus.
C. Halley’s Comet has a highly eccentric orbit.
D. The Sun is located at the center of a planet’s elliptical orbit.
E. The eccentricity of Mars’s orbit is zero.
The question discusses the historical breakthroughs in understanding the solar system, notably by Copernicus followed by improvements by Kepler. Misconceptions about the shape and nature of planet orbits (eccentricity and elliptical shape) are the main theme. Not all given statements about planets' orbits are correct.
Explanation:The subject matter in this context is primarily talking about the work of Copernicus and the discovery of better understanding of the solar system through the concepts of orbits. Terms like 'eccentric' and 'elliptical' orbits are being used which reference to the shape of the paths that planets follow around the sun. Statement A, B, and C are correct and based on Kepler's first law of planetary motion. Option B is not correct because it's not the sun and the planet that constitute the foci of the ellipse but the sun and an empty point in space. Option D is not correct because the sun is not at the center of the elliptical orbit but at one focus. And statement E implies that the Mars's orbit is a perfect circle - which is untrue, since no planet has a perfectly circular orbit; all planets have orbits with a certain degree of eccentricity.

Consider the following processes: respiration, combustion, polymerization, nitrification, industrial fixation, and photosynthesis. How many of these result in the release of oxygen into the atmosphere?
Answer:
The answer to the question "How many of the processes result in the release of oxygen into the atmosphere?" is only one of them does it: photosynthesis.
Explanation:
The photosynthesis occurs mostly inside plants. During this process, the plant needs carbon dioxide, light and water in order to release oxygen into the atmosphere.
The respiration is a process where oxygen is consumed and carbon dioxide is released into the atmosphere.
The combustion involves two participants: a fuel and an oxidizer. During this process, oxygen is consumed too and new chemical substances are created. Also, it generates heat during the process.
The polymerization is a process where simple molecules form chains and become more complex and bigger molecules. There are different types of this reaction and some of them use oxygen when they are forming bigger molecules. To conclude, this process do not release oxygen into the atmosphere.
The nitrification is a process that is made mainly by bacteria. During this process, those organisms need to use oxygen from the environment to be able to transform ammonia to nitrate. This is an important step to enrich the soil, but it do not release oxygen.
The industrial fixation is not a natural process. During this synthetic reaction, atmospheric nitrogen is transformed into nitrogen oxides or ammonium ions that bacteria can use in nitrification. It consumes oxygen too.
Final answer:
Out of the processes listed - respiration, combustion, polymerization, nitrification, industrial fixation, and photosynthesis - only photosynthesis results in the release of oxygen into the atmosphere.
Explanation:
During photosynthesis, plants convert carbon dioxide and water into glucose and release oxygen as a byproduct, thus enriching the atmosphere with oxygen. The balanced chemical equation for photosynthesis is 6CO2 + 6H2O + Light Energy
ightarrow C6H12O6 + 6O2, clearly showing the production of oxygen. None of the other processes mentioned, such as respiration, combustion, or nitrification, release oxygen; in fact, they consume oxygen and produce carbon dioxide. Respiration is the process where organisms use oxygen to break down glucose into carbon dioxide and water, releasing energy. Combustion is the burning of substances in oxygen, resulting in the release of carbon dioxide. Polymerization does not involve any exchange of gases with the atmosphere. Nitrification is part of the nitrogen cycle where ammonia is converted into nitrite and then nitrate, and industrial fixation, similar to the Haber process, is about synthesizing ammonia, neither contributing to atmospheric oxygen.

Although greenhouse gases likely account for the problem of global warming, they are also responsible for making earth habitable. What would be the temperature on earth in the absence of the effects of carbon dioxide and water?
Answer:
-18°C
Explanation:
Global warming takes place due to the constant increment of atmospheric gases caused by human activities, and these include CO2, CH4, N20, and CFC. These are commonly known as greenhouse gases because they allow for the major part of solar radiation to enter the atmosphere and heat the surface of the Earth. At the same time, they avert a part of thermal radiation from escaping to space. If these effects caused by greenhouse gases and water did not exist, the average temperature of the Earth would be around -18°C (0°F), but instead, it is about 15°C (59°F).
What percentage of the solar energy that reaches the marsh is incorporated into gross primary what percentage of the solar energy that reaches the marsh is incorporated into gross primary production?
In a cattail marsh, only 2.2% of the solar energy that reaches the plants is captured for gross primary productivity, and at least half of this energy is used by the plants themselves.
The percentage of solar energy that reaches the marsh and is incorporated into gross primary productivity is a measure of how much of the sun's energy is captured by photosynthetic organisms for growth and reproduction. In the case of a cattail marsh, the plants trap only 2.2% of the solar energy that reaches them. Notably, three percent of the energy is reflected, while a substantial 94.8% is used to heat and evaporate water. Importantly, only a fraction of the captured energy, which is the net primary productivity, is available to other organisms in the ecosystem as at least half of the 2.2% trapped is utilized for the plants' own metabolic processes.
Which of the following is correct?
a.The age of the seafloor decreases as you move away from the mid oceanic ridge
b.The age of the seafloor increases as you move away from the mid oceanic ridge
c.The age of the seafloor is the same in most areas
d.The age of the seafloor does not follow a discernible pattern
Answer:
A. The age of seafloor decreases as you move away from the mid oceanic ridges.
Explanation:
The scientist can determine the age of the seafloor by evidence collected by dating the rocks found near the seabeds, the rocks that were found far away from the mid-oceanic ridges and seafloor were considered to be of the old or ancient period as compared to the rocks that were seen near the surface of the ridges. This is because the spreading of lavas, on or near the surface of the ridges creates lava plumes that tend to move up and these on cooling down get settled with the same magnetic patterns or alignment that of earth. Thus distant rocks have different age compositions due to the molten matter that forms the basaltic rocks in tectonic plates.Each of the following diagrams shows a spaceship somewhere along the way between Earth and the Moon (not to scale); the midpoint of the distance is marked to make it easier to see how the locations compare.

___________ biome contains a nutrient-rich environment created by falling leaves and trapped organic materials from the large trees, and it provides the ecosystem service of filtering pollutants from water.
The temperate forest is the biome described. It is characterized by deciduous trees that create a thick layer of leaf litter, contributing to a rich nutrient cycle and ecosystem services such as filtering pollutants from water.
The biome that contains a nutrient-rich environment created by falling leaves and trapped organic materials from large trees, which provides the ecosystem service of filtering pollutants from water, is the temperate forest. In the temperate forest, deciduous trees dominate and form a thick layer of leaf litter on the forest floor when they shed their leaves. This leaf litter is crucial for maintaining a rich nutrient cycle and offering protection against soil erosion. Moreover, it insulates the ground and serves as a habitat for various invertebrates like the pill bug (Armadillidium vulgare) and their predators, such as the red-backed salamander (Plethodon cinereus). The nutrient cycle in temperate forests is characterized by the decomposition of the leaf litter, which returns inorganic and organic nutrients back to the soil, thereby enhancing its fertility and providing an integral ecosystem service by filtering pollutants from water.

Answer:
C.
Explanation:
Geothermal renewable energy has declined in recent years.
Explanation:Geothermal energy is generated by the high temperatures within the earth's core. Though it has been used as an energy source for a long time, it has declined in recent years due to the increase of other use of renewable and non-renewable energy.
The efficiency of geothermal energy supply is also not reliable and there are cost implications to think about. The geothermal reserve in most location is in places that are far from people, therefore, transportation costs become high. There are also pumping costs, high electricity cost per megawatt, etc.
You are halfway between the equator and the South pole and one-quarter of the way around the Earth to the west of the Prime Meridian. What is your latitude and longitude?
Answer:
All of the lines of longitude to the west of the prime meridian until 180 degrees are in the western hemisphere. Ninety degrees west is a line that passes through North America, including Lake Superior and the Yucatan Peninsula.
You are located at 45 degrees south latitude and 90 degrees west longitude, as you are halfway between the equator and the South Pole and a quarter of the way around the Earth west of the Prime Meridian.
If you are halfway between the equator and the South Pole, that means you are at 45 degrees south latitude, because the South Pole is at 90 degrees south latitude. When you are one-quarter of the way around the Earth to the west of the Prime Meridian, given that a full circle is 360 degrees, a quarter of that would be 90 degrees. Since you are west of the Prime Meridian, your longitude would be 90 degrees west. Therefore, your complete coordinates would be 45°S latitude and 90°W longitude.

Having an average density of 2,7 g/cm, primarily being composed of denser rocks like basalt and gabbro from below. Mostly it's basaltic, from here all sorts of rocks are recycled to the outer land surface of the earth. Accounting for nearly 60% of the global slab of plates. Apart from this, the seafloor is covered with volcanic necks, trenches and deep-seated volcanoes that produce magma and the oceanic floor is composed of layers of rocks that date back to the various epi, meso, bathy, and abyssopelagic divisions.Precipitation that has a pH lower than 5 will result in acid deposition. One result of this deposition has been damaged forests at high elevations in the southern Appalachian mountains. How would acid deposition cause this damage?
Answer:
Acidic rain can damage the soil, leaves, and severely impact the air quality.
Explanation:
Acidic rain contains sulfur content which is quite harmful to the soil and air and decreasing their ability to photosynthesis, also this rain causes loss of critical nutrients from the soil. When lakes and streams become acidic they kill the fish population as they are sensitive to the acid reaction. These streams that are higher elevations receive a greater amount of rainfall as compared to the lower streams. The toxic rain causes aluminum, lead and other harmful chemicals to escape and mix with the soil layer deep below in additional the acid from the acidic clouds and fog that often surround them thus leading to a high concentration of acid deposits.Name the two longest rivers in the united states?
