Explanation:

Modified True/False

1.

In the US, the most abundant fossil fuel is coal, not natural gas. So the statement is false; change "natural gas" to "coal".

Nonrenewable resources like fossil fuels form over millions of years (very slow) while we use them quickly, so they are nonrenewable as their formation rate is much slower than usage rate. The statement is true.

Growing population and new products (like cars) increase resource use, so saying "has not increased" is false. Change "has not increased" to "has increased".

Answer:

False; change "natural gas" to "coal"
