An ecosphere is a completely closed and balanced ecosystem.

Our ecosphere includes the physical earth, all of the organisms living on it, and all of the environmental factors which act on the organisms.

Ecosphere is also used as a synonym of biosphere and as a term for zones in our universe where life as we know it should be sustainable.

The Earths physical ecosphere is made of of three (3) primary parts:

• Geosphere – all rocks, minerals, and landforms on Earth’s surface
• Hydrosphere – all the waters on the Earth’s surface
• Atmosphere – all the gases within Earth’s bubble
