Question

Why can a heavy rain showers cause a large amount of erosion in a desert area

Answer 1

There is a lack of vegetation to hold the soil in place.

Answer 2

Major rainfall events can cause majorerosion, especially because the desertdoes not have a covering of vegetation to protect it. But rainfall is infrequent in deserts and in between storms, there will be continuous abrasiveerosion by wind-blown sand.
