question 4 of 10
what is the main reason why soil erosion can be a problem for people?
a. people need soil to build houses.
b. people need soil to grow plants.
c. people use soil to stop weathering.
d. people use soil to block the wind.

Explanation:

Soil is crucial for plant growth as it provides nutrients, support, and water - holding capacity. While soil can be used in some construction (but not the main reason for its importance in a general sense), it cannot stop weathering (weathering is a natural process) and is not the main material for blocking wind (other structures like windbreaks made of plants or man - made barriers are more common).

Answer:

B. People need soil to grow plants.
