The following are examples of interactions among spheres of the earth. Next to each scenario, explain which sphere is interacting runoff from farming areas into local streams

The four spheres of the Earth includes the Geosphere, Hydrosphere, Biosphere and Atmosphere. The sphere that there is interaction in runoff from farming into the local areas is on Hydrosphere. Hydrosphere is the liquid water component of the Earth. It includes the oceans, seas, lakes, ponds, rivers and streams.

In the above example, the Lithosphere, that is the crust of the Earth, not the Geosphere is interacting with the Hydrosphere as surface runoff from land is entering into the water in streams.
