Our Natural ResourcesOur Natural Resources• Resources found naturally in
nature– Cannot make more, but can be renewed
– Natural Resources essential for living• Oxygen• Water
Kinds of Natural Kinds of Natural ResourcesResources
A nonrenewable resource is a natural resource that is present in limited supplies and depleted by use. It's basically a limited resource that we are extracting from the ground faster than it can replenish itself. (9) Examples of nonrenewable resources are copper, gold, silver, zinc, aluminum, coal, oil and natural gas.
ExhaustibilityExhaustibility• Whether or not the supply of a
resource is replenished as it is used.
• Some resources can be replenished; others cannot be replenished.
Inexhaustible ResourcesInexhaustible Resources• Resources that are continually
being replenished.– Examples:
• Sunlight• Air & Wind• Water
Exhaustible ResourcesExhaustible Resources• Resources that are available in
limited quantity that can be used up.– Examples:
• Minerals• Fossil Fuels• Soil (replaced so slowly)
Words to know and rememberas you consider what
resources are renewable
InfiniteNo limitsExtending
indefinitely
FiniteLimited
Having a limited existence
ConservationConservation• Using resources wisely.
– Resources are not abused, wasted nor destroyed.
– “Wise” is using a resource in ways that do not diminish its value and assure that supplies will be available for future generations.
• SUSTAINABLE RESOURCE USE is using resources so they last a long time.
PreservationPreservation• Maintaining a natural resource
without using it up.– Resource is protected.– Set aside for future use.– People can view the resource, but cannot
harvest, mine or otherwise take it.– Examples:
• Wildlife Preserves and Refuges• Old Growth Forests protected from cutting
Earth's natural resources need to stay healthy too!
Assignment Assignment • You and a partner will make a list of all
the resources that can be either: – Preserved
– Sustainable
– Conserved
– Exhausted
– Inexhaustible
• Then you will explain why they are one of the five categories above and can they be renewed or are they nonrewable.
WATER- inexhaustible Renewed
To clean the atmosphere and the environment, and to nourish plants and animals.
SOIL- exhaustible Renewed
To filter the water, provide nourishment for plants and some animals, and recycle material to be used again.
PLANTS AND TREES- exhaustible To absorb carbon from the atmosphere and release oxygen.To supply food and medicine, and provide shelter for plants and animals.
ATMOSPHERENonrewable Air surrounding the planet containing nitrogen, oxygen, water vapor, other gases, and many tiny particles.
To protect life on the planet, shielding it from harmful radiation from the sun.To provide a blanket of warmth around the planet.
