Why are there tremendous amounts of erosion when it rains in a desert?

What will be an ideal response?


Answer: Rainfall usually comes out of fierce thunderstorms which have great rainfall intensities making great potential for runoff. Many surfaces have little soil, are impervious, and so accelerate the erosion capability of the runoff. Finally, there is little vegetation to slows and encourage infiltration at the expense of runoff.
