Answer 1

B, C and D

Step-by-step explanation:

Fossil fuels include coal, petroleum, natural gas, oil shales, bitumens, tar sands, and heavy oils. When fossil fuels are burned, they release large amounts of carbon dioxide, a greenhouse gas, into the air.

Although fossil fuels are continually formed by natural processes, they are classified as non-renewable resources because they take millions of years to form.

fossil fuels, are called nonrenewable, which means they have a limited supply and are not continuously being made or they are made very slowly
