Aresource, such as soil or trees, that can be replaced by the earth’s natural processes is called a resource.
a. renewable
b. nonrenewable
c. expendable
d. fossil fuel

The correct answer is A. Renewable

Explanation:

A renewable resource refers to any resource that can be replaced over time usually because it is naturally produced and it never runs out under natural circumstances. This includes solar energy, trees or soil that do not run out because they are naturally produced all the time. This concept differs from nonrenewable sources such as coal or natural gas that exist on Earth in a limited quantity, cannot be replaced naturally or takes a lot of time for nature to produce them. Considering this, in the case of soil or trees that are replaced naturally this is a Renewable source.
