Warm Up: Top of 30 Which elements, besides water, make up the human body? Nitrogen Carbon Oxygen
Earths Major Components NBpg. 31 Earths Major Components Slide 1 of 3 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. Video Note (2:17) Video Note Hydrosphere – WATER & ICE- All the water on or near the earth’s surface (liquid, ice, water vapor).

Earths Major Components (Cont.) NBpg. 31 Slide 2 of 3 Earths Major Components (Cont.) Geosphere – ROCK & MINERALS- Consists of the earth’s hot core, thick mantle, and outer crust. Video Note (3:20) Video Note Biosphere – ORGANISMS- On Earth where life exists. Video Note (3:42) (Q3) https://www.youtube.com/watch?v=N3EqcUNdIl8
Earths Major Components (Cont.) NBpg. 31 Slide 3 of 3 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 (Q4) Summary
