Back

The four main spheres of Earth are the geosphere (land), hydrosphere (water), atmosphere (air), and biosphere (living things).

What is the hydrosphere?

Back

The hydrosphere includes all the water on Earth, such as oceans, rivers, lakes, and water vapor in the atmosphere.

Front

What is the geosphere?

Back

The geosphere is the solid part of Earth, including rocks, soil, and landforms.

Front

What is the atmosphere?

Back

The atmosphere is the layer of gases surrounding Earth, essential for weather and climate.

Front

What is the biosphere?

Back

The biosphere is the part of Earth where life exists, including all living organisms and their environments.

Front

How do the hydrosphere and geosphere interact?

Back

Water from the hydrosphere can erode rocks and soil in the geosphere, shaping landscapes.

Front

How do the biosphere and geosphere interact?

Back

Plants in the biosphere grow in the soil of the geosphere, relying on nutrients and minerals.

Front

How do the atmosphere and geosphere interact?

Back

Wind from the atmosphere can move sand and soil in the geosphere, causing erosion.

Front

How do the hydrosphere and atmosphere interact?

Back

Water vapor from the hydrosphere forms clouds in the atmosphere, influencing weather patterns.

How do the atmosphere and biosphere interact?

Back

Wind in the atmosphere can help spread seeds from plants in the biosphere.
