Earth Systems
- The atmosphere
- the biosphere
- the hydrosphere
- the geosphere
- a blanket of air
- 4 unique layers
- troposphere
- stratosphere
- mesosphere
- thermosphere
- over 350 miles above earth
- mostly nitrogen (78%) and oxygen (21%)
- the life zone
- all living organisms and organic matter
- hierarchy known as food chain
- energy and nutrients are transferred
- all the water on the earth
- Surface water-oceans, lakes, rivers
- Ground water- trapped in the soil
- Atmosphere- water vapor
- Frozen water- ice caps and glaciers, cryosphere
- only about 3% is fresh water, and 70% is frozen
- solid, from core to surface
- includes volcanoes, rocks, minerals, coal, oil
