Answer 1

Answer:

1. Weathering is the breakdown of rocks and minerals at the earth's surface.

Factors that affect the rate of weathering and soil erosion:

a. Heavy Wind: Winds add pressure on soil and rocks because of which rocks break down and soil wears away

b. Rainfall: rainfall causes rocks to break down and soil to wear away easily

c. Temperature: Extremely hot temperature breaks down rocks faster than cold temperature
