is made of decomposed plant matter in conditions of high temperature and pressure.

Coal

7

is not a uniform substance either, it's composition varies from deposit to deposit.

Coal

8

Factors that cause this deviation are:

-the types of original plant matter,
-the extent the plant matter decomposed.

Stratospheric ozone depleters

21

Gases that stay in the air for a long time and warm up the planet by trapping sunlight.

Greenhouse gases

22

Why is it called the “greenhouse effect”?

because the gases act like the glass in a greenhouse.
