NATURAL RESOURCES

TODAY’S OBJECTIVE

By the end of today’s lesson:
• We should be able to classify

natural resources as being

renewable, non-renewable or

inexhaustible

Open Ended

Why do you think we call coal, oil and natural gas fossil fuels?

Natural Resources

A Natural Resource is something made by

nature that people need or use.

Natural Resources

Natural resources include: water, sunlight,
fossil fuels, plants, animals, metal, air, rocks

and soil

Some
natural

resources

come

from the

earth

Natural resources

Why are natural resources important?

Coal, oil, natural gas and sunlight provide

energy for humans

Renewable Resources: Soil, freshwater,

plants (trees), animals, sunlight and air

Non- Renewable

Resources

Renewable Resources

Natural Resources are put into 2 groups

Non-Renewable Resources: Fossil fuels such

as coal, oil and natural gas, minerals and

metals such as aluminum, copper and iron

Non- Renewable

Resources

Renewable Resources

Natural Resources are put into 2 groups

Renewable resources are resources that

can be replaced in a relatively short

amount of time

Renewable resources

Multiple Choice

Which one of these is a renewable energy source?

• COAL

• HYDRO POWER

• FOSSIL FUELS

• SMOKE

renewable resources

Plants are renewable resources because
when old plants die, new plants quickly
grow in their place

renewable resources

Soil is produce relatively quickly by

weathering of rocks

renewable resources

Freshwater is always being replaced by

the water cycle

renewable resources

Nonrenewable resources

Nonrenewable resources take a long time

(millions of years) to be replaced

Nonrenewable resources

Fossil fuels such as coal, oil and natural

gas are nonrenewable resources

FOSSIL FUELS

Nonrenewable resources

Nonrenewable resources

Fossil fuels are forms of stored energy that
were formed when plant and/or animals

remains were trapped deep inside the

earth’s surface

FOSSIL FUELS

Natural Gas

Oil

Coal

FOSSIL FUELS

The heat and pressure deep in the earth
changes the plants and animal remains

into coal, oil or natural gas

Fossil Fuels

Coal is formed from the plant remains
that were buried by layers and layers of

sediment for several million years.

FOSSIL FUELS

COAL

FOSSIL FUELS

COAL

Over time heat and pressure cause the
remains to become a solid called coal

FOSSIL FUELS

COAL

FOSSIL FUELS

OIL (PETROLEUM)

Crude oil is formed when heat and

pressure acts on plant and sea animal

remains

FOSSIL FUELS

These remains were buried under the

ocean over millions of years in the

absence of air

OIL (PETROLEUM)

FOSSIL FUELS

These organic remains eventually

become oil

OIL (PETROLEUM)

Multiple Choice

WHAT 2 THINGS ARE NEEDED TO CREATE OIL AND COAL?

• DIRT AND GAS

• PRESSURE AND WATER

• HEAT AND PRESSURE

• HEAT AND GAS

Natural gas is commonly used as a source of heat for cooking

FOSSIL FUELS

NATURAL GAS

Natural gas is formed from the remains

of dead plants and animals

Natural
gas is

formed in
the same
way as oil

FOSSIL FUELS

NATURAL GAS

As sediments deposit on top of the

organic remains, heat and pressure forms,

changing them into natural gas

Multiple Choice

WHAT ENERGY SOURCE DID MR. MIMS PRESENT?

• NUECLEAR POWER

• HYDRO POWER

• AIR

• SOLAR

FOSSIL FUELS

NATURAL GAS

Why are fossil fuels important

Why are fossil fuels

important?

Coal is burned in factories to produce
steam that powers electric generators

Coal is

also

burned to

power
steam
trains

Coal is used as a
fuel—that is, it is

burned to produce

energy

COAL

Why are fossil fuels important

Why are fossil fuels

important?

Coal can also be burned to

produce heat in buildings

Nonrenewable resources

COAL

Why are fossil fuels

important?

The crude oil that is drilled from the

ground is refined to produce petroleum

products such as gas used in cars

Nonrenewable resources

OIL (PETROLEUM)

CRUDE OIL

REFINED OIL

Why are fossil fuels

important?

NATURAL GAS

Natural gas is used for cooking, drying

clothes and also in water heaters.

FOSSIL FUELS

Nonrenewable resources

Because fossil fuels take millions of years
to make, they are impossible to replace
and are called nonrenewable resources

Natural gas
oil

coal

Nonrenewable resources

Metals and minerals, formed naturally in
the earth, are non-renewable because

they take millions of years to form

Nonrenewable resources

METALS

Multiple Choice

REFRESHER: METALS ARE KNOWN TO BE:

• CONDUCTORS

• INSULATORS

• TRANSITORS

• BRITTLE

NATURAL

RESOURCES

Renewable
resources

They take a log

time to be
replaced

They can be

replaced in a short

amount of time

Nonrenewable

SUMMARY

which means that

RESOURCE CONSERVATION

Because non-renewable resources can

run out and cannot be replaced in a
short time, we have to use them wisely

This is called

resource

conservation

RESOURCE CONSERVATION

Resource

Conservation
means that
people use

resources more

carefully to

make them last

longer.

Reduce, Reuse and

Recycle

RESOURCE CONSERVATION

We must reuse and recycle plastics, can
and other natural resources so that we
can use the old ones again and again

This makes the resources last longer and

not run out quickly

RESOURCE CONSERVATION

We must also avoid cutting down too

many trees because trees provide

oxygen for us

RESOURCE CONSERVATION

When fossil fuels are burned in excess, they

can cause air pollution

POLLUTION

POLLUTION

Sometimes when we use natural

resources, we produce waste that can

be toxic to the environment

This is
called

POLLUTION

POLLUTION

Pollution can happen in the air, in our

water bodies or on the land

Smoke causes air pollution. It comes from
cars, trucks and factories

air pollution

Burning fossil fuels also produces lots of
carbon dioxide that destroys the ozone

layer and increases global warming

FOSSIL FUELS

air pollution

Air pollution can lead to acid rain which
destroys plants

air pollution

Acid Rain

Land pollution

Land pollution occurs because of too

much trash

The trash piles up in landfills

Factories

dump waste
into rivers and
seas and this
causes water

pollution

water pollution

Pollution affects the fish and plants in the
water

water pollution

water pollution

Poll

TRUE or FALSE: Fossil fuels take thousands of years to form?

• True

• False

Open Ended

Why should we use alternative or renewable energy?

Burning fossil fuels like coal to make
electricity makes our natural
resource run out quicker

Burning fossil fuels
also pollutes the
environment by
producing carbon
dioxide

Because of these problems with using

fossil fuels, the United states is now

looking into using alternative or

renewable energy sources to produce

electricity.

ALTERNATIVE ENERGY

The use of alternative or renewable
energy benefits the environment
because it is generated from natural
renewable resources such as sunlight,
wind, rain, tides, geothermal heat, and
animal and plant products.

ALTERNATIVE ENERGY

Using alternative energy helps to prevent

pollution and also global warming

Alternative energy however can have

very high start up costs.
