21.2 Quiz Renewable and Nonrenewable resources

What are renewable resources?

• Resources that can be replaced in a short amount of time

• Resources that are used faster than they can be replaced

• They can not be replaced

Answer explanation

Renewable resources are those that can be replenished naturally in a short amount of time, such as solar or wind energy. This distinguishes them from non-renewable resources, which are consumed faster than they can be replaced.

What are Nonrenewable resources? 

• Resources that can be replaced in a short amount of time  

• Resources that are used faster than they can be replaced
