Science · Earth's Systems · conceptual

Sign in to track this

What mastery looks like

  • Name the four Earth systems: geosphere (rock/land), hydrosphere (water), atmosphere (air), biosphere (living things)
  • Describe at least two interactions between different Earth systems with examples
  • Create or interpret a model showing how a change in one system affects others

Check your understanding

Can Earth's atmosphere explain how rain (atmosphere) falls on mountains (geosphere), flows into rivers (hydrosphere), and provides water for plants and animals (biosphere)?
