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, retained by gravity, which is essential for life.

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 hydrosphere interact?

Back

The biosphere and hydrosphere interact through processes like photosynthesis, where plants use water from the hydrosphere.

Front

What role does evaporation play in the atmosphere and hydrosphere interaction?

Back

Evaporation brings water from the hydrosphere into the atmosphere, contributing to weather patterns.

Front

What is condensation in the context of Earth's spheres?

Back

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

Front

How does the atmosphere affect the hydrosphere?

Back

The atmosphere affects the hydrosphere by influencing weather and climate, which can change water temperatures and levels.

Front

What is the relationship between the geosphere and biosphere?

Back

The geosphere provides nutrients and minerals to the biosphere, supporting plant and animal life.
