Earth Resources


2/16

Natural resources are materials andenergy that come from the naturalworld and are valuable to us.

Natural resources include rocks,

minerals, soil, water, andatmospheric gases.

Natural resources also includedifferent types of energy such as

solar energy, geothermal and thekinetic energy from wind and water.

Inexhaustible Resources Inexhaustible resources are

those materials that cannot

be used up for millions of

years. They are continuousand always available for

human use.

Human activities have no

impact on them.


5/16

Inexhaustible Resources

Examples of inexhaustibleresources are solar energy,

tidal forces, ocean currents

and wind energy.


6/16

Examples of InexhaustibleResources The energy from the Sun is predicted to

be available for another 5 billion years.

Solar energy gives us light, heat andpowers the wind and ocean currents.

The gravitational pull of the moon

powers the tides and this pull iscontinuous.


7/16

Nonrenewable Resources Nonrenewable resources take millions of years

to form. Because of the time it takes to reform

them, they are considered nonrenewable.Once these resources are used up they are

considered gone.

Non-renewable resources are rocks, minerals,

oil and coal. Almost all of the energy that humans use

comes from this type of resource.


8/16

Fossil Fuels (non-renewable)

Fossil fuels, oil, coal and naturalgas were formed from buriedprehistoric plants and animalsover millions of years.

These resources can beextended by recycling, using less,and reusing them, but theycannot be replaced.

Example: Oil is used to makegasoline, plastics, fertilizers, andpesticides.


9/16

Minerals (non-renewable) Minerals form very slowly. They are

the main component of rocks.

Some products produced fromminerals are glass, iron, aluminum,

copper, gold, silver, diamonds, rubies,

and pigment for paint.


10/16

Rocks (non-renewable) Rocks are made from different

types of minerals and form

slowly.

Some materials manufacturedfrom rocks are building

materials, concrete and cement.

Extraction of minerals from rock

through mining also depletes therock reserve on Earth


11/16

Renewable Resources Renewable resources can be replaced in

a relatively short period of time.

They reproduce or renew themselves.Water, soil, plants, animals and

components of the air are considered

renewable.


12/16

Water(renewable) Water is renewable because it

passes through the water cycle. Precipitation is recycled and brings

water to the soil, oceans, aquifers,

lakes, and streams.

Moving water can be used to create

electricity.


13/16

Soil (renewable) Soil is a combination of organic materials and

tiny bits of weathered rock.

Soil takes longer to renew than water, plants,

or animals. New soil can form in a few years from decaying

plant and animal products, bacteria andworms. Humans can speed up soil formation

by composting. Generally, forming soil from decaying organic

matter takes less time than the weathering anderosion of rock material.


14/16

Air (renewable)

Air is a combination of atmospheric

gases. Different components of theair are renewable.

The carbon dioxide/oxygen cycle and

the nitrogen cycle renew the gases.


15/16

Plants and Animals(renewable) Plants such as grasses,

crops, and trees renew

themselves.

Animals have many usesand are considered

renewable as they

reproduce.

Both plants and animalsneed protection from

extinction.
