EQ: How do Earth’s major components work together to support life?
The Earth’s Life-Support System Has Four Major Components
Atmosphere – AIR- A thin spherical envelope of gases surrounding the earth’s surface.

Earths Major Components (Cont.)
Matter is not created or destroyed, it is transformed, the same molecules pass through via cycles.
In organisms, more than 95% of the body is made up of just four elements.
Oxygen, Carbon, Hydrogen, and Nitrogen
These elements are passed from one organism to another and from one part of the biosphere to another through biogeochemical cycles.
The Water Cycle
The Carbon Cycle
The Nitrogen Cycle
