1 Spheres of the Earth Atmosphere Biosphere Hydrosphere Lithosphere

2 Atmosphere The Earth is surrounded by a blanket of air, which we call the atmosphere. It absorbs the energy from the Sun, recycles water and other chemicals and protects us from high-energy radiation. The envelope of gas surrounding the Earth changes from the ground up. Four distinct layers have been identified using thermal characteristics (temperature changes), chemical composition, movement, and density.

3 Layers of the Atmosphere Thermosphere—highest Mesosphere Stratosphere (contains ozone) Troposphere---layer we live in

4 Earth as a System Can you think of any other spheres that interact with the biosphere? Atmosphere? Hydrosphere? Lithosphere?

5 Hydrosphere The hydrosphere includes all water on Earth.

6 Hydrosphere

7 Earth as a System Can you think of any other spheres that interact with the biosphere? Atmosphere? Biosphere? Lithosphere?

8 Lithosphere The lithosphere is the solid part of the Earth. (soil)

9 Earth as a system Can you think of any other spheres that interact with the atmosphere? Biosphere? Hydrosphere? Lithosphere?

10 Biosphere The term "Biosphere“ is the life zone of the Earth and includes all living organisms, including man, and all organic matter that has not yet decomposed.

11 Biotic vs. Abiotic Bio = means life Biotic—living parts or components Abiotic—nonliving parts of components (air, water, temperature)
