You will have questions asking for an example of how 2 spheres interact.

​

It is asking for an example of how one sphere affects a different sphere.

For example:

​

If a volcano erupts and it ejects a large amount of CO2 gas into the air what two spheres are interacting?

9 of 13

A volcano is an example of the geosphere.

​

Gas is an example of the atmosphere.

For example:

​

If a fish lives in the ocean what two spheres are interacting?

11 of 13

A fish is an example of biosphere.

​

The ocean is an example of the hydrosphere.

Now you try.

​

Think of an example of something from the BIOSPHERE interacting with something from the ATMOSPHERE.

Now you try.

​

Think of an example of something from the HYDROSPHERE interacting with something from the GEOSPHERE.
