Nonrenewable resources are natural resources that cannot be replaced quickly once they are used. These resources form over very long periods of time, often millions of years. They include materials such as coal, oil, and natural gas. Once used, they are not easily available again.

Nonrenewable resources are found in Earth’s crust in different regions around the world. They are taken from the ground and used for energy and materials. These resources are part of many industries and daily uses.

Because they take so long to form, nonrenewable resources are limited in supply. They have been used by humans for many years. These resources continue to be used in many parts of the world today.
