Answer:
The crust size remains constant because the older crust is melted at subduction zones.
Explanation:
The crust is constnatly created on Earth, but the crust is constantly getting destroyed as well. This situation leads to the total size of the crust being roughly at the same level, or rather constant, as one side a new one emerges, while at the same time, on the other side it gets destroyed.
The vast majority of the new crust is formed where there are divergent plate boundaries. Here, a gap opens up between the plates that move away and magma is constantly rising to the surface and creates new crust. When it comes to the destruction of crust, it occurs at subduction zones. Here, one plate moves below another plate, and as it does it reaches the upper mantle where it gets melted and recycled because of the high temperatures and pressure.
The answer for this question is B: HydroElectric Power
Answer: As a creator, one can understand the changes in the environment and can create an animal according to those changes.
Explanation:
The animal can experience change in temperature, difficulty in obtaining food, mates, water, and shelter. Animal that lives in cold environment must have thick coat, thick fur, hard claws so that cold ice cannot be felt by the animal, must have similar color as that of the snow or ice so as to protect oneself from the predators by mimicking the color of the ice, or can camouflage prey by remaining undetected. Animal must have appreciable amount of fat to keep the body insulated in otherwise cold environment. Such an animal can also hibernate when there is extreme cold condition.
