Question

which of the following statements explains why fossil fuels are nonrenewable resources? fossil fuels form underground more quickly than they are used by humans. it takes millions of years for fossil fuels to form.

Explanation:

To determine why fossil fuels are nonrenewable, we analyze the options:

• The first option ("Fossil fuels form underground more quickly than they are used by humans") is incorrect. If they formed faster than use, they could be renewable.
• The second option ("It takes millions of years for fossil fuels to form") is correct. Nonrenewable resources are replenished very slowly (geological timescales, like millions of years) compared to human usage rates. Since fossil fuels take millions of years to form, their supply is finite on human timescales, making them nonrenewable.

Answer:

It takes millions of years for fossil fuels to form.
