Earth's Atmosphere & CO2

Science · Matter & Materials · conceptual

Describe the composition of Earth's atmosphere (mainly nitrogen and oxygen, with small amounts of CO₂ and other gases), explain how human activity increases CO₂, and describe the impact on global climate

What mastery looks like

  • States the approximate percentages of nitrogen, oxygen, CO₂, and argon in the atmosphere
  • Explains how burning fossil fuels and deforestation increase atmospheric CO₂
  • Describes the greenhouse effect and how it leads to climate change
  • Discusses one specific consequence of climate change (e.g. rising sea levels, extreme weather)

Check your understanding

If Earth's Atmosphere & CO2 was asked why scientists are worried about CO₂ levels rising, could they explain what CO₂ does in the atmosphere, why human activities produce more of it, and what effects it's having on the planet?
