Question

Suppose that you were asked to compare rates of sediment erosion on two land surfaces: a steep, forested mountain slope; and a flat, grassy plain. Which of the following statements about erosion rates at the two locations is correct?
a. Erosion is greater on a flat plain because the gentler slopes

b. Erosion is less because the mountain is covered by a thick layer of clay

c. erosion is less on the mountain because of the abundant rainfall

d. Erosion is greater on the mountain slope because the higher water velocities
​

Answer 1

Answer: d. Erosion is greater on the mountain slope because the higher water velocities

Explanation:

The erosion can be defined as the loss of fertile top layer of the soil due to the action of physical agents like water, wind, and others. The mountain slope will offer less resistance against the movement of the materials like soil, sediments, pebbles, stones, and others down the slope. The water will also flow at higher velocity without any resistance on the mountain slope and it will erode the top layer of soil along with other materials like sediments, pebbles, stones, and others.
