Answer: Splash erosion is the first stage of the erosion
process. It occurs when raindrops hit bare soil. The
explosive impact breaks up soil aggregates so that
individual soil particles are ‘splashed’ onto the soil
surface.
Sheet erosion is the removal of soil in thin layers
by raindrop impact and shallow surface flow. It
results in loss of the finest soil particles that
contain most of the available nutrients and organic
matter in the soil.
gully erosion is when the water movement is powerful enough to increase the channels to larger gully pathways greater than 3/10 of an inch, that is when gully erosion occurs. This type of water erosion can be caused by rainfall or melting snow as it moves. It occurs in areas where runoff water accumulates and flows quickly.
