Key Points to Remember

A natural resource is something from Earth that people use.

Air, water, land, rocks, minerals, and soil are natural resources that people use in many ways.

Think of how people use some of those natural resources.

Rocks are nonliving things made of one or more minerals.

Soil is made of bits of minerals and rock, rotting plants, and rotting animals.

Plant roots help protect soil from being taken away by wind and water.
