An island arc forms where ____.
oceanic crust collides with continental crust
oceanic crust diverges from continental crust
continental crust collides with continental crust
continental crust diverges from continental crust
oceanic crust collides with oceanic crust
Answer:
oceanic crust diverges from continental crust
Explanation:
An island arc forms where oceanic crust diverges from continental crust.
An island arc forms where oceanic crust collides with oceanic crust. The collision leads to subduction, where the denser plate goes underneath the other. The subduction process causes volcanic activity that creates a chain of islands known as an island arc.
Explanation:An island arc refers to a string of volcanic islands that typically form in the ocean due to tectonic plate activities, specifically at subduction zones. These zones are areas where one tectonic plate is forced to dive or 'subduct' beneath another plate. An island arc specifically forms where oceanic crust collides with oceanic crust.
When this collision occurs, the denser of the two plates sinks beneath the other in the mantle, forming a deep-sea trench. The subducted crust then begins to melt due to the intense heat and pressure in the mantle. This melting generates magma, which rises to the surface and creates a chain of volcanoes. Over time, repeated volcanic eruptions lead to the emergence and growth of islands above the sea surface, hence forming an island arc.

In a species with incomplete dominance, the genotypic and phenotypic ratios will be ___________.
A. The inverse of each other (3:1, 1:3)
B. identical (1:2:1, 1:2:1)
C. different (3:1, 1:2:1)
D. unable to be compared.
Answer:
correct option is b identical (1:2:1,1:2:1)
Explanation:
In order to assess the most likely results of the crosses for those genes that display incomplete dominance, Mendel's model can be is used because these genes are acquired in retained with Mendel's fundamental rules, even if they all exhibit incomplete dominance. This can be clarified by adopting an instance of green crop inter-fertilization producing a feasible 1:2:1 genotype ratio and 1:2:1 phenotype ratio.
so correct option is b identical (1:2:1,1:2:1)

How many times taller is the Eiffel Tower than an average Human?
Explanation: The Eiffel Tower was set up on March 31, 1889, in Paris on the centenary of the French Revolution. Designed by Gustave Eiffel, an engineer, this tower is 324 meters high, including an antenna, weighing around 10,000 tons. According to statistics from 2018, the average human height in America is 175.4 cm, which may be taken as the relevant data given the diversity of races in America. This means that the Eiffel Tower is taller than the average human about 185 times.
By using the average human height of 2 meters and the original height of the Eiffel Tower at 321 meters, we can calculate that the Eiffel Tower is 160.5 times taller than an average human.
Explanation:To determine how many times taller the Eiffel Tower is compared to an average human, we first need to establish the average height of a human. As mentioned in the reference, we can take the average height of an adult to be about 2 meters tall. The Eiffel Tower has an original height of 321 meters. By dividing the height of the Eiffel Tower by the height of an average human, we get the number of times the Eiffel Tower is taller.
Calculation:
321 meters (height of Eiffel Tower) ÷ 2 meters (height of average human) = 160.5 times.
Therefore, the Eiffel Tower is 160.5 times taller than an average human.

The earliest land on Earth probably formed at? Choose one: mid-ocean ridges. hot spots convergent continental collisions. subduction zones.
Answer:
hot spots
Explanation:
The earliest land on Earth formed as a result of the volcanic activity, or hot spot volcanism to be more specific. The hot spots managed to lift up the ocean floor with their activity, and gradually volcanic islands started to form. As these islands grew more and more because of the lifting up of the volcanoes, as well as the lava flows that they released, this started to merge, thus giving birth to the first continental land mass on Earth. The rocks that initially formed this first land mass are believed to have been ultramaffic because of the greater amount of heat that was present on Earth in that period of time.

With regard to wind circulation patterns, the Northern and Southern Hemispheres are
mirror images of each other.
a. True
b. False
Answer:
a. True
Explanation:
The prevailing wind patterns on the Northern Hemisphere and Southern Hemisphere, despite not being the same, are actually a mirror image of each other. The mirror image shows the same at both sides, but this can lead to a confusion when it comes to the wind patterns. What seems to be the same, is actually because the winds have the opposite directions, so the winds that move from northeast toward southwest are moving from the southeast toward northwest.
Cleavage in minerals refers to ________. a. a tendency to break in an irregular pattern b. a tendency to break along planes of weakness c. the sharpness of edges between crystal faces d. the development of well-formed crystal faces
The correct answer is B. I hope this helps! Best of luck to you! :)
Cleavage in minerals refers to a tendency to break along planes of weakness. Hence, option B is correct.
What is Cleavage in minerals?Cleavage is the propensity of minerals to split along crystallographic planes, resulting in planes of relative weakness. This is caused by the structural locations of atoms and ions in the crystal.
To determine the angle of cleavage, look at the intersection of the cleavage planes. Cleavage planes typically intersect at 60°, 90°, or 120° angles to straight angles. When observing flat surfaces on minerals, keep in mind that not all of them are cleavage planes.
The tendency of a material to fracture on flat planar surfaces depends on the mineral's crystal structure. These two-dimensional surfaces, referred to as cleavage planes, are produced by the alignment of atoms with weaker interactions within the crystal lattice.
Thus, option B is correct.

A tsunami is considered to be a:
Capillary wave
Deep water wave
Reflected wave
Refracted wave
Shallow water wave
Answer:
Shallow water wave.
Explanation:
A tsunami is considered to be a shallow water wave.
Final answer:
A tsunami is a shallow water wave typically caused by seismic activities underneath the ocean. While inconspicuous in deep water, tsunamis become significantly larger and more dangerous as they reach shallower coastal waters.
Explanation:
A tsunami is considered to be a shallow water wave. These waves are commonly initiated by disturbances such as undersea earthquakes, landslides, or volcanic eruptions. When in deep ocean, a tsunami's height can be less than 30 cm, allowing it to travel at speeds up to 700 km/h largely unnoticed. As it approaches the coast and enters shallower waters, its speed decreases, and it grows substantially in height due to the energy being compressed into a smaller column of water. The Indian Ocean tsunami of 2004, caused by an immensely powerful earthquake, is an example of the devastating effects when a tsunami reaches populated coastlines.
Regarding the distance between wave crests at sea for a tsunami traveling at 600 km/h with a frequency of one wave crest every 15 minutes: to find this, you multiply the speed of the wave by the time interval between crests. Since there are 60 minutes in an hour, a 15-minute interval is a quarter of an hour (0.25 h). Therefore, the distance between crests would be 600 km/h × 0.25 h = 150 km.

The many parallel ridges and valleys of the large Basin and Range region of the western United States are the result of normal faults.
True
False
Answer:
The given statement is True
Explanation:
Generally, basin and range areas of the world are mostly the direct outcome of the geological factors that underlie most notably -tectonic extensions. These have started 17 million years back and are the outcome of lithosphere and earth crust being pulled apart due to tectonic movement. By the passage of time with progressive crust movement, it became stretched and thinner to a point where fracture can occur due to faults. Such faults are the outcome of normal faults. Western United States have a vast region covering its inland which is characterized by abrupt elevation changes, varying between flat arid basins to faulted and narrow chain of mountains.

Water’s high heat capacity allows the ocean water to be:
•• Cooler than the land around it.
•• Warmer than the land around it.
•• The same temperature as the land around it.
•• Sometimes warmer, sometimes cooler than the land around it.
Answer:
Water’s high heat capacity allows the ocean water to be:
Cooler than the land around it.
Explanation:
Water has high heat capacity of 4.18 J/g ° C , i.e. it consumes more amount heat to warm gram of water . water has the ability to absorb more heat. During warm summer day, the water temperature in the oceans does not change that much as compared to the land. Land on the other hand has much low heat capacity, so it is more warmer.
For this reason, the ocean takes a longer time to increase temperature whereas land will heat quickly. The air which is in contact with the oceans will be cooler. Therefore, the ocean water is cooler than the land around it.

Explanation: As transform plate boundary is the surface where the plates present slides from side of each other this is why deep ocean trenches are not adjacent to it. Lithosphere at the transform plate boundary does not get created or destroyed.They are usually found near the sea floor.They are also considered as the main reason behind the natural calamities like tsunami ,earthquakes etc.
why are you more likely to see convective clouds form on the afternoon rather than in the morning?
Answer: During the day, especially in the afternoon, layers of air heat up, which is needed to create convective clouds
Explanation: Convective clouds, as the name implies, are created by convection. It is a process of raising warmer air of lower density than is the case with the surrounding atmosphere. Warm air contains more moisture, i.e. water vapor than cold, and when warm air rises during the day, it passes through layers of cooler air, causing water vapor to condense, creating droplets. During the morning, the air is generally cold, and during the day due to the rise in temperature, certain layers of air become warm, which then begin to rise and pass through the surrounding, cooler layers. Thus, the said condensation process takes place.
The mineral we call diamond is the hardest known substance on Earth. Explain why attaching small pieces of diamond to the tips of saw blades and drill bits makes the best type of tools for cutting through hard objects.
Explanation: Diamond is one of the forms of carbon compounds, where carbon atoms are arranged in a crystal structure, called a diamond cube. Thus, the arrangement of carbon atoms in a three-dimensional diamond cube with very strong covalent bonds is why the diamond is a very tough mineral. Due to this structure, the diamond is a huge covalent compound where each carbon atom is joined by four other atoms, and then the atoms form a very regular tetrahedral structure. It should be said that in the diamond there are no free electrons and other free particles, so the diamond does not conduct electricity. In order to break up very strong covalent bonds between carbon atoms, a very high temperature is required, so the diamond has a very high melting point. Therefore, the diamond is used for attaching to the top of saw blades and drilling tools due to its high hardness and high temperature resistance. It is also used as an abrasive for polishing, in the oil and mining industry.
The thermocline is a layer in the ocean that represents:
•• Density change due to mixing.
•• Density change due to salinity.
•• Density change due to temperature.
•• Constant density due to salinity
Answer:
The thermocline is a layer in the ocean that represents:
Density change due to temperature.
Explanation:
A thermocline is a thin distinctive layer in a large body of fluid which is exactly located between warmer mixed water at the top of ocean surface and cooler deep water at the bottom of ocean surface. Salinity is defined as the total amount of salt dissolved in water.
The water in the ocean or sea forms into layers according to density. Water with high density sinks at the bottom while water with low density sits on the top. And the density of water changes with salinity and temperature. Higher salinity leads to higher density, and the water changes rapidly with depth.
Final answer:
The thermocline in the ocean is a layer that signifies a density change due to temperature, where warmer water sits over colder water, creating a stable, stratified environment.
Explanation:
The thermocline is a layer in the ocean that represents a density change due to temperature. This layer is characterized by a temperature that is significantly different from that of the surrounding layers, usually warmer water at the top and colder water below.
As the wind stirs the upper layers, it creates a mixed layer at the surface with constant temperature and salinity. Below this mixed layer is the thermocline, typically between about 200 - 1000 m depth, where the temperature decreases rapidly with depth, leading to an increase in water density. This temperature-driven density change is crucial for the ocean's vertical structure and affects oceanic currents and marine life distribution.
The most prolific corals in the reef systems of the Paleozoic were the schleractinians. Select one: O True False
Answer:
I believe the answer is false.
Explanation:
Notice the newly constructed seawall in the illustration below. The MOST likely outcome of its construction is that the seawall will a.temporarily protect the cliff from beach erosion. b. permanently protect the home from beach erosion. c. increase sediment production on the beach, decreasing the rate of erosion. d. deter biologic activity that might compromise the integrity of the cliff.
The most likely outcome would be a.temporarily protect the cliff from beach erosion.
Here's the reason why:
As sea wall's construction material is likely to be rock, no matter it's weather-resistance, it would be weathered by different weathering agents, especially in area with relatively high rainfall and humidity. Sea water itself will also catalyse the weathering process by chemical weathering, or physical weathering such as hydraulic action or abrasion.
When the sea wall is not properly maintained or has been in use for a prolonged period, it may be worn off and no longer able to serve as a protection to the cliff.
Therefore, it is a temporary measure to protect the cliff from beach erosion.
Why the other reasons are false:
b. permanently protect the home from beach erosion.
-As mentioned, the seawall can not last forever due to weathering and erosion that can damage the sea wall, the answer is therefore false.
c. increase sediment production on the beach, decreasing the rate of erosion.
-While sea wall may indeed be weathered and produce sediments from the construction material, or slightly help the sediment to accumulate, it is unlikely that it can decrease the rate of erosion effectively.
d. deter biologic activity that might compromise the integrity of the cliff.
Although it is possible to construct a sea wall to prevent biological activity of the cliff, such as the growth of vegetation or being inhabited by creatures, which can damage the integrity of the cliff, a sea wall without proper maintenance may not be able to deter these activities. Besides, it is possible for creatures to reside or plants to grow in sea wall, thus it is not the most likely outcome.
Hope it helps!
The newly constructed seawall is likely to temporarily protect the cliff from beach erosion.
Explanation:The newly constructed seawall in the illustration is likely to temporarily protect the cliff from beach erosion. Seawalls are designed to act as a barrier between the ocean and the land, reducing the impact of waves on the shoreline. However, over time, the seawall itself can cause changes in sediment movement and erosion patterns.

3. Many species of butterflies are noxious to predators. They also have bright red coloration that indicates to the potential predators that they are unpleasant or even harmful to eat. This is an example of _______ coloration.
A) aposematic
B) cryptic
C) mimic
D) predative
1. C) Species diversity
It is not easy to perform any measurement about the species, be it its diversity, richness, or evenness. The easiest though seems to be the measuring of species diversity. This measurements simply gathering information about the number of species in a particular area, which is usually the easiest thing to do, as at least one individual of a species is needed so that it can be added in the measurement. The species richness and evenness though are harder, as in order to be performed, apart from knowing all the species, there should be measurement about how big of a population the species have, which can be very tricky, and in some cases almost impossible to perform, which is why it is often used a mathematical model to predict an approximate number, which often is not correct.
2. A) They can consist of biotic changes associated with a boundary
The edge effects are effects that occur at the boundaries of the biomes. At this boundaries, the two or more biomes that come in contact interact, start to mix and create a zone where there are representatives of both biomes, kind of like a transitional zone. Because around the boundary there are species from both bomes, changes start to occur, as the species adapt to the conditions, but they also change the living conditions, as well as competing with each other which can further affect one of the biomes and its structure.
3. A) aposematic
The butterflies tend to have aposematic coloration. This type of coloration does not provide camouflage for the butterflies, but instead it makes them stick out. It is a coloration where the colors are few and very intense. The reason why the butterflies have this type of coloration is that it is a sign of warning for the predators that they are not good for eating and that they can be harmful, thus to avoid them. The predators usually learn this from a young age, and tend to avoid the butterflies that have such coloration.
