Earth's FOUR Systems

• ​​Planet earth is like an enormous puzzle.

• It has different parts that all work together.

• ​These parts are called spheres.

• Earth has four spheres: Geosphere, hydrosphere, atmosphere, and biosphere.

• These four spheres are contiually working together and interacting. Everything on Earth can be placed into one of the four systems.
