Earth's History Practice Questions

Outgassing is the

• Expelling of gasses out of our atmosphere by sunlight

• Release of gasses from Earth's interior due to internal heat and chemical reactions

• Release of CO2 from early plants

• Production of gas as water and hydrogen combine in the atmosphere

The development of oxygen in Earth's early atmosphere came from

• The rapid evolution of trees

• Chemical reactions with free oxygen in the atmosphere

• Photosynthesis of early plants and algae

• Filtering of the gasses in the atmosphere by the ozone layer
