Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water),...

Explains what the four spheres of the Earth are, and the interactions between them.

Students learn to identify the parts of the Earth system and the processes that connect them. They look for interconnections among components of the Earth system at the local level, using a study site close to their school.

Explains what the four spheres of the Earth are and describes how volcanic eruptions affect the different spheres. Also provides a list of events that are examples of interactions.
