Soil Material that supports all living things –Naturally occurring resource –Basis for all living things –Plants need soil to grow –Animals eat plants –Remains decay and become soil again –Damaged and lost by erosion
Minerals Natural inorganic substance on or in the earth. –INORGANIC SUBSTANCE Does not have the structure of living things, does not contain carbon. –Examples: Iron Precious Metals (Copper, Gold, Silver, Nickel) Granite, Sand, Gravel
Assignment You will make a chart of all 8 Natural Resources and how they are important to you –Must have: The name of all the Natural Resources Picture of it Why it is important to you –They must be in color and neatly done
Renewability Whether or not a resource can be restored after it has been used. Basis for classifying natural resources: –Renewable –Nonrenewable
Renewable Resources Can be replaced when used. –Resource may renew itself and be used again, but renewing may take a long time –Examples Air Soil Wildlife Plants Water
Nonrenewable Resources Can not be replaced when used. –With careful management, some can be reused. –Examples Minerals (Gold, Silver) Fossil Fuels (Oil and Coal)
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.coal, oil and natural gas
Exhaustibility Whether or not the supply of a resource is replenished as it is used. Some resources can be replenished; others cannot be replenished.
Inexhaustible Resources Resources that are continually being replenished. –Examples: Sunlight Air & Wind Water
Exhaustible 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 remember as you consider what resources are renewable Infinite No limits Extending indefinitely Finite Limited Having a limited existence
Conservation 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.
Preservation 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 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.
ATMOSPHERE Nonrewable 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.
