Why are farming practices like terraced fields important in terms of soil conservation?

A. They help limit the amount of soil that is produced, which is essential because soil is a
renewable resource.

B. They prevent soil from eroding and becoming lost, which is essential because soil is a nonrenewable resource.

C. They remove pollutants from the soil, which is essential because living things depend on pollutant-free soil.

D. They cause nutrients in the soil to leak out, which is essential because plants need nutrient-
poor soil.
