12

The Greenhouse effect

The process by which certain gasses (principally water vapor, carbon dioxide, and methane) trap heat that would otherwise escape the earth and radiate into space

13

What are the ways that oxygen is taken from the air?

Ozone formation, rusting metals and minerals, fire, and respiration ( main )

14

What are some ways oxygen is added to the air?

Ozone destruction, water vapor destruction, photosynthesis (main)

15

What are some ways carbon dioxide is taken from the air?

Dissolving into ocean, photosynthesis (main)

16

What are some ways carbon dioxide is added to the air?

Fuel burning, decomposition, and respiration (main)

17

What is nitrogen fixation?

It changes nitrogen gas into a reactive molecule
Preformed by nitrifying bacteria
