Renewable Resources• Definition- a resource that can be replaced in a
short amount of time.

Examples of Renewable Resources
• Fresh Water via the water cycle• Plants via the life cycle• Animals via the life cycle• Air via the process of photosynthesis• Soil via decomposition of matter and bacteria

SoilSoil is dynamic and is filled with all kinds of life… such as microbes, worms, fungi, insects, roots and more. It contains minerals and small rocks that vary in size from that of silt to pebbles. Soil also usually contains organic matter which is the decaying remnants of plant and animal life.It can take hundreds or thousands of years to make 1 inch of soil

Inexhaustible (HUH?) Resources
• Definition- resources that cannot be used up.
• Oh wait……scientists don’t classify resources an inexhaustible….so keep going with– RENEWABLE!!

Examples of MORE Renewable Resources
• Wind• Ocean Tides• Sunlight

Wind
Wind can be harnessed to store energy as electricity or used directly to pump water

Ocean Tides
The movement of the tides could be harnessed withan underwater turbine to store the energy.

Sunlight
We can use sunlight to generate electricity by using solar panelsand we already know that the sun is the energy source for the waterand for photosynthesis.

What Can We Conclude About Earth’s Resources?
• How do we classify earth’s resources?• What are some examples of each type of
resource?• Should we be more careful with two types of
resources than the other one?• What can we as individuals do to help conserve
some of our most important resources?
