Answer 2

Answer:

From what I know I'm almost positive its burning coal.

Explanation:

Once coal is mined, it must be cleaned and processed at special plants to remove dirt, rock, and other unusable parts. These plants release many toxic chemicals into both water and air. Other chemicals, such as carbon dioxide (CO2) and sulfur dioxide (SO2) are released when coal is burned. Carbon dioxide is the main greenhouse gas.
