REVIEW 6.10A

By Stephanie Ramirez

• Geosphere → rocks, soil, magma, land
• Hydrosphere → all water (liquid, solid, gas)
• Atmosphere → gases around Earth (air, clouds, rain, water vapor)
• Biosphere → all living things

If it’s alive → biosphere

​Earth’s Four Spheres

Sphere Interactions

Sphere Interactions
• Earth’s spheres do NOT work alone
• A change in one sphere causes changes in others

Examples:
• Volcano erupts → ash in air (atmosphere) → harms animals (biosphere)
• Ash falls in ocean → affects water (hydrosphere)
• Rain washes soil → hydrosphere + geosphere
• Plants hold soil → biosphere + geosphere

Atmosphere Key Facts

Atmosphere Key Facts
• Made of gases like oxygen and nitrogen
• Includes clouds, rain, and water vapor
• Is layered
• Densest layer is closest to Earth

• Biosphere = living
• All other spheres = nonliving
• Geosphere & atmosphere are both layered
• Only the biosphere contains organisms

Compare & Differentiate

Open Ended

Infer:

A volcano erupts, releasing ash into the air and sea. How might this affect the biosphere, atmosphere, and hydrosphere?

Open Ended

Differentiate:

How is the biosphere different from the hydrosphere, geosphere, and atmosphere?
