what makes crude oil a nonrenewable resource?
a. when burned, it contributes to global warming.
b. when burned, it adds pollutants to the air.
c. it takes millions of years to form.
d. it can be replenished within a persons lifetime.

Explanation:

Non - renewable resources are those that form over extremely long periods, much longer than a human lifetime. Crude oil takes millions of years to form, which classifies it as non - renewable. Options A and B describe the environmental impacts of burning crude oil, not why it is non - renewable. Option D is incorrect as it implies renewability within a human lifetime.

Answer:

C. It takes millions of years to form.
