Earth is comprised of four systems, or spheres. describe how these four systems work together as a system.

Hydrosphere - All water on Earth

Biosphere - All life on Earth

Lithosphere - Solid ground on Earth

Atmosphere - Invisible gases surrounding Earth.

These 4 systems rely heavily on each other in order for them to function. For example, the biosphere wont be able to exist if it wasn't for the hydrosphere doing the water cycle
