Answer:
B. A steep slope
Explanation:
The rate of erosion is the highest on barren lands and on steep slopes. The steep slopes are much more easy to erode because the gravity is pulling downwards, and the angle of the slope is helping that a lot. Also, the steeper the slope is, the less vegetation there is, thus the soil usually is not protected from erosion. When there's rain, snow, stronger winds, they manage to pull down the soil with ease as there's nothing that is an obstacle to stop them. That results in gradual leveling up of the slope, constantly losing on height, and eventually being totally flattened.
Global warming causes danger to human health and well-being, as well as to animals and plants. As global warming is mainly caused by anthropogenic activities, it was considered that emission of the so-called greenhouse gases should be reduced and in some cases even prohibited. Plants are more easily exposed to biological damage than any other living organisms.
