Biogeochemical Cycles NBpg. 29 Biogeochemical Cycles (biology + geology + chemistry) 9/11/2018 EQ: Explain how all components work together to support life. The Earth’s Life-Support System Has Four Major Components Atmosphere - A thin spherical envelope of gases surrounding the earth’s surface. Hydrosphere - All the water on or near the earth’s surface (liquid, ice, water vapor). Saltwater ~71% Freshwater ~2% Geosphere - Consists of the earth’s hot core, thick mantle, and outer crust. Biosphere – On Earth where life exists. (Q1) (Q2)

Biogeochemical Cycles (Cont.) NBpg. 29 Biogeochemical Cycles (Cont.) Matter is not used up, it is transformed, the same molecules are passed around. 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 (Q3) (Q4) Summary
