To store all of Earth’s water
To create mountains and volcanoes
How does the biosphere interact with the geosphere?
Plants grow in soil and animals dig burrows in the ground
The atmosphere provides oxygen for animals
Water from the hydrosphere falls as rain
The sun provides energy for life on Earth
What is weathering?
The breaking down of rocks into smaller pieces
The movement of clouds across the sky

It is unlimited and never runs out
It is essential for drinking, farming, and daily life
It only exists in the ocean
How do the hydrosphere and atmosphere interact?
The atmosphere provides oxygen for the geosphere
Water evaporates from oceans and forms clouds in the atmosphere
The geosphere holds up the biosphere
Animals breathe in water from lakes
What happens when Earth's spheres interact?
They work separately without affecting each other
