2.  Natural gas forms when sea organisms die and lay on the ocean floor.  They are buried to make sediment, over time, the sediment is compacted and slowly becomes rock.  Through physical and chemical changes, millions of years later, the rock becomes natural gas.  It is a nonrenewable resource because it takes a very long time for it to form.  Humans have used this resource since 2008.  When it is burned it creates energy.

3.  Very flammable  Gas leaks can lead to fires or deadly explosions.  Takes millions of years for sea life to become natural gas.  Contributes to the green house effect.

4.  Causes less air pollution then oil  Easier and safer to store  Domestic production of natural gas lessens our dependency on foreign oil  Ongoing process

5.  For camp stoves.  Outdoor grills.  Some motor vehicles use natural gas for fuel.  Electrical energy.

6.  When water falls on he water wheel it turns to create energy.  This resource is renewable because water constantly cycles.  Humans have used this resource for thousands of years.

7.  Building dams for this can and will destroy other resources such as forest and wildlife habitats  Disrupts the migratory paths of local populations of salmon and steel head  Decreases water quality  Creates erosion problems  It is not available everywhere

8.  Reduces the demand for fossil fuels  Inexpensive  Causes little pollution  Large dams can capture enough water to generate significant amount of electrical energy  Ongoing process

9.  For electrical energy  In current accounts about 20% of earths electrical supply is from hydropower  Makes machines work  Provides electricity for our homes
