Answer:

Raindrops can cause soil erosion.

Step-by-step explanation:

When the soil is without vegetation, whether it is alive or dead, if a rain occurs, it is highly vulnerable to erosion. This is due to the kinetic energy (or energy of the falling motion) of the raindrops. Raindrops act by "bombarding" the soil, causing it to disintegrate. As a result, aggregates of soil particles are disrupted by the impact of raindrops and the particles that compose it begin to settle on the soil surface, reducing the pores that absorb water in it.

Thus, with less pores to absorb water, there is a decrease in the rate of water infiltration into the soil, which is more likely to run on the soil surface in a process called runoff that, in tropical regions, is the major cause of erosion. of the soils. This "attack" by raindrops on bare soil causing disintegration of its structure is called splash erosion and the reduction of infiltration due to clogged pores from the soil surface is known as surface sealing due to the formation of surface crusting. .
