How do the hydrosphere and geosphere interact?

Back

Front

What is an example of the atmosphere and hydrosphere interacting?

Back

An example is rain falling from clouds, which is part of the water cycle.

Front

What is an example of the biosphere and geosphere interacting?

Back

An example is plants growing in soil, where the biosphere (plants) relies on the geosphere (soil).

What role do humans play in the biosphere?

Back

Humans are part of the biosphere as they are living organisms that interact with other life forms and the environment.
