Front

How do the biosphere and atmosphere interact?

Back

Plants in the biosphere take in carbon dioxide from the atmosphere for photosynthesis, demonstrating the interaction between these two spheres.

Front

What role does the hydrosphere play in Earth's systems?

Back

The hydrosphere regulates climate, supports life, and is involved in geological processes like erosion and sediment transport.

Front

What is the cryosphere?

Back

The cryosphere includes all the frozen water on Earth, such as glaciers, ice caps, and sea ice.

Front

How does fire affect the atmosphere?

Back

Fire releases gases and particulates into the atmosphere, impacting air quality and climate.

Front

What is an example of interaction between the hydrosphere and geosphere?

Back

Rivers (hydrosphere) eroding rocks and soil (geosphere) as they flow.

Front

What is the significance of the geosphere in supporting life?

Back

The geosphere provides essential minerals and nutrients for plants and animals, forming the foundation for terrestrial ecosystems.
