What are some examples of nonrenewable resources?

Back

Examples of nonrenewable resources include coal, oil, natural gas, and minerals like phosphate and limestone.

Front

What is the difference between renewable and nonrenewable resources?

Back

Renewable resources can replenish naturally in a short time, while nonrenewable resources take millions of years to form and cannot be replaced quickly.

Front

What is luster in minerals?

Back

Luster refers to the way light reflects off the surface of a mineral, indicating its shine or dullness.
