Question:
The major agent of erosion in deserts today is
a. glaciers.
b. wind.
c. abrasion.
d. running water.
e. none of the previous answers.
Erosion:
Erosion is a natural process taking place on the Earth's surface, wherein the top surface of the land washes away by specific physical means, such as water and wind. Gully erosion, splash erosion, sheet erosion, etc., are a few of the classifications of erosion.
