INTRODUCTION TO NATURAL RESOURCES Objective: By the end of this lesson students will be able to know and understand what the 8 natural resources are.

Our Natural Resources Resources found naturally in nature –Cannot make more, but can be renewed –Natural Resources essential for living Oxygen Water

Kinds of Natural Resources Wildlife Air Wind Soil Water Minerals Fossil Fuels Sunlight

Wildlife Plant, animal, and any other thing that lives in the wild. –NOT domesticated –Examples: Fungi Wild flowers Trees Insects Fish Snakes

Air Mixture of gases that surrounds the earth. –Most important Natural Resource –All living things must Oxygen is the most important of air

Los Angeles County air exceeds EPA air pollution standards by 70%.

Wind Large-scale air movement across the earth surface –Wind power is harnessing wind movement. Windmills and Turbines collect the power and use it to pump water, generate electricity, etc.

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

Water Colorless, transparent, odorless, tasteless liquid that forms the seas, lakes, rivers, and rain All living things must

–Only natural resource found in 3 forms –Solid (ice) –Liquid (water) –Gas (vapor) –Flowing water can be used as a power source

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

Fossil Fuels Materials used to provide energy –Created by the decomposition of plants and animals –Three main groups: –Petroleum (gas, oil, plastics) –Natural Gas –Coal

Sunlight Light and warmth of the sun –Produces solar energy –Used by plants in photosynthesis –Life on earth depends on sunlight

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.
