Interactions among Earth's spheres

Front

What are the four main spheres of Earth?

Back

The four main spheres of Earth are the biosphere, hydrosphere, atmosphere, and geosphere.

Front

What is the biosphere?

Back

The biosphere is the part of Earth where life exists, including land, water, and the atmosphere.

Front

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 atmosphere?

Back

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

Front

What is the geosphere?

Back

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

Front

How do the biosphere and geosphere interact?

Back

The biosphere interacts with the geosphere when plants and animals decompose, returning nutrients to the soil.

Front

What role does the hydrosphere play in climate?

Back

The hydrosphere influences climate by regulating temperatures and weather patterns through evaporation and precipitation.

Front

What is evaporation?

Back

Evaporation is the process where water changes from a liquid to a gas, entering the atmosphere.

Front

What is condensation?

Back

Condensation is the process where water vapor cools and changes back into liquid water, returning to the hydrosphere.

Front

How do the atmosphere and hydrosphere interact?

Back

The atmosphere and hydrosphere interact through processes like evaporation and precipitation, affecting weather and climate.
