1. Hydrosphere

2. Hydrosphere
All of the liquid, solid and gaseous water contained on the surface, within the ground and in the atmosphere

3. So, what does this include?
Everything!!!
Oceans
Lakes
Rivers
Icecaps
Glaciers
Soil
Rocks
Clouds

4. How does water move through the environment?
Precipitation – Water that falls to the surface from the atmosphere
Rain, snow, sleet, hail
Evaporation – The change of state from a liquid to a gas
Condensation – The change of state from a gas to a liquid
The Water Cycle

11. What’s all this other stuff???

12. Transpiration – The evaporation of water through plants

13. Evapotranspiration – The sum loss of water through evaporation and transpiration

14. Sublimation – The change of state from a solid to a gas.

15. How many oceans are there?

16. How many oceans are there? Oceans are all interconnected, World Ocean
70% of earth’s surface

17. Oceans as a Temperature Regulator
Oceans absorb most of the solar energy that reaches the surface
Gulf Stream
Great Britian 54oN latitude
Same as Newfoundland, Regina, Saskatchewan
Ocean currents redistribute energy
Oceans absorb and release energy more slowly than land
Moderates atmospheric temperature changes

20. Biosphere
The narrow band around the earth’s surface in which all life exists
12km into the ocean, 9km into atmosphere
Most organisms require :
Liquid Water
Moderate Temperatures
Source of Energy
Exceptions:
Extremeophiles, hydrothermal vents

21. Extremophiles

22. Extremophiles

23. Extremophiles

24. THE EARTH IS A CLOSED SYSTEM
Closed System – Energy comes and goes, matter stays
Open System – Energy and matter are exchanged with other systems
THE EARTH IS A CLOSED SYSTEM
