This gas makes up 78% of the atmosphere

• oxygen

• nitrogen

• ozone

• carbon dioxide

Over Geologic Time, Earth's atmospheric oxygen levels have:

• Increased

• Decreased

• Fluctuated

• Stayed at a constant %

Earth's atmosphere accumulated oxygen primarily due to:

• Land plant respiration

• Microscopic organisms' respiration

• Mamma (human) respiration

• Volcanism
