Cause global dimming as they prevent sunlight from reaching the Earth’s surface.
Also cause lung damage in humans.

Question 4

most fossil fuels contain…

Answer 4

Sulfur compounds. When the fuel burns, these sulfur compounds produce sulfur dioxide.
At the high temperatures produced when these fuels burn, oygen and nitrogen may combine in the air to form nitrogen oxides.
Sulfur dioxide and nitrogen oxides cause acid rain and breathing problems in humans. Acid rain damages trees, kills animal and plant life in lakes and attacks limestone buildings and metal structures.
