1. Energy Sources

4. Energy Resources
The lithosphere contains natural resources we can use to create energy. The resource turns a turbine and generates electricity.
Fossil fuels (oil, coal and natural gas)
Non-renewable, releases greenhouse gases
Uranium
Non-renewable, does not release greenhouse gases, nuclear waste
Geothermal
Renewable, does not release greenhouse gases, limited in location

12. Hydroelectric Dam
Converts hydraulic energy from a river or waterfall into electrical power
See your power sheets for more information

13. Wind Energy

14. Solar Energy

15. Solar Energy

16. Tides High Tide = Water high
The water on Earth closest to the Moon are gravitationally attracted and swell (rise)
The water on the opposite side also swell due to inertia
Low Tide = Water low
Occurs on the sides that are not facing or opposite the Moon
Tidal range = difference between water level at high and low tide

19. Tides There are two high tides and two low tides in a day
Spring tide = combined tides when Moon and Sun are aligned
