Earth's Systems (Sphere's)

The solid part of Earth covered with non-living rock, soil, minerals and landforms.

• biosphere

• geosphere

• cryosphere

• magnetosphere

The system (sphere) of Earth that is believed to have began 3.8 billion years ago where animals, bacteria, fungi, protists and plants are located.

• cryosphere

• atmosphere

• geosphere

• biosphere

Located on, under or above Earth's surface, this system (sphere) may be a liquid, solid, or gas.

• Ecosphere

• Atmosphere

• Hydrosphere

• Mesosphere

This system (spheres) can be considered the sibling of the hydrosphere because it contains frozen water.

• biosphere

• cryosphere

• geosphere

• atmosphere

The system that surrounds the geosphere, biosphere and hydrosphere and contains nitrogen, oxygen, and argon.

• atmosphere

• biosphere

• lithosphere

• hydrosphere
