What are natural resources?

•Natural resources are living and nonliving
things from the biosphere, geosphere,
hydrosphere, and atmosphere.

•They are used by living things to meet their
needs, such as for food and shelter.

Can you identify the natural resources used to make
a common object?

Can you find one object in the classroom that does not come from natural
resources?
Explain.

No, you cannot find an object that does not come from natural resources because everything
we use comes from resources.

make up objects from your classroom.

Timber, oil, metals, or minerals.

7. What type of natural resource was most common? Why might this be?

Wood was the most common natural resource. It was used in books, desks,
tables, pencils, and other classroom objects.

What are natural resources?

Natural Resources
Life on Earth, such as this plant,
requires the use of resources.

The term resource covers everything
we use, including such basic assets as
air, soil, timber, and water;

Fuel resources, such as coal, oil, and
gas; and mineral resources, such as
sand and gravel.

Let’s explore how humans depend on
different types of natural resources.

How do humans depend on energy resources?

In the United States today, the energy used for
most daily activities is easily available at the flip
of a switch or the push of a button.

How do you use energy in your daily activities?

How do you personally get energy to move, play, and
do other activities?

How do cars, planes, and other types of vehicles get

Textbook # 12

How do humans depend on energy resources?

Energy Resources

Energy can come from sunlight, fossil
fuels, flowing water, or other sources.
The power for lights, computers,
appliances, and other electrical devices
comes from energy resources. Nearly all
manufactured products are made using
energy resources.

Energy resources provide the fuel you
need to get from one place to another,
whether it’s in a car, bus, plane, or boat
and can keep you warm in cold weather
and cool in warm weather.

How do humans depend on energy resources?

Petroleum, natural gas, propane, and coal are fossil
fuels.

Ancient plants stored radiant energy from the Sun as
chemical energy in their molecules. This chemical energy
was passed on to the animals that ate the plants.

Over millions of years, geological processes converted the
remains of these ancient plants and animals into fossil fuels.

Fossil fuels are a very concentrated form of chemical energy
that easily transforms into other forms of energy.

How do humans depend on land resources?

Chances are, when you walk into your kitchen a
majority of the items you touch, see, taste, and
smell had roots in the land.
Let’s explore how items in your home are
connected to land resources.

Why is land considered a resource?

Land is something from Earth that is used to meet the
needs of living things.

Multiple Choice

Land is a natural resource because it is used by living things to meet their needs.

• True

• false

4. Why do you think land is considered a resource?

Make a list of items in a kitchen that come from land resources.

Cast iron skillet , pots, pans, steel appliances bowls , glass cups, marbled

countertop, beverage cans , salt, fruits, vegetables , cabinets

Land is a source of supply and support for all living things including

humens

How do humans depend on land resources?

Land Resources

People use land to grow food and for grazing
animals.
The wood →furniture, paper, cardboard, and other
timber products comes from forests that cover the
land. We build on land. We live and play on top of it.

Land provides us with living space. People use
land to create green spaces, or areas of natural
vegetation in urban landscapes. Some land is also set
aside for use as wilderness preserves and national
parks.

Development is limited in these places.

How do humans depend on land resources?

Certain minerals are mined to make products you use
every day. These minerals often are called ores.

Ores are deposits of minerals that are large enough
to be mined for a profit.
The average person uses 22,000 kg of mineral
resources each year.

For example, copper is used in electric wiring
and plumbing fixtures, and quartz is used to make
glass and ceramics.

The automotive industry; agriculture and food
production; and road, home, and building
construction use mineral resources. These resources
are mined from Earth.

Multiple Choice

A mineral is classified as an ore as long as ____.

• it is rare and valuable

• it can be used as jewelry

• it is profitable and useful

• it is solid and natural

How do humans depend on air and water resources?

Water is a crucial resource for living
things. Like air, we cannot survive without
it.

In most places in the United States, people are
fortunate to have an adequate supply of clean
water. When you turn on the faucet, do you
think about the value of water as a resource.

How do humans depend on air and water resources?

Importance of Air and Water

Using some natural resources, such as fossil fuels and minerals, makes life easier. You would
miss them if they were gone, but you would still survive.

Air and water, on the other hand, are resources that you cannot live without. Most living
things can survive only a few minutes without air. Oxygen from air helps your body provide
energy for your cells.

How do humans depend on air and water resources?

Importance of Air and Water

In addition to drinking water, people use
water for other purposes, including
agriculture, transportation, and
recreation.

People use freshwater for drinking and other
daily uses, such as cooking and cleaning. In
addition to soil, plants need water to grow.
Freshwater is used to irrigate crops. Water is
also used for mining, manufacturing, and
generating power. Rivers, lakes, and oceans
are used to transport goods and people from
place to place.

Seafood is a major source of protein for many
people around the world. Fish and seafood are
harvested from oceans, lakes, and rivers.

How do humans depend on air and water resources?

Activity

Textbook # 21

Humans depend on Earth’s geosphere for land resources and
energy resources such as timber, minerals, and fossil fuels.

Humans depend on Earth’s hydrosphere for water resources such
as freshwater and Earth’s atmosphere for air.

How long
will natural
resources
be around?

How long will natural resources be around?

Every day you use energy resources when you
turn on lights or play a video game.

You use water resources when you brush your
teeth. You eat plants grown on land. You go
places in a bus or car made from minerals and
powered by energy resources. And you inhale
and exhale air every minute of the day.

Is there an infinite supply of natural
resources, or could we someday run out of
them?

❖ What would your life be like if we ran out of resources?

Life could not exist without resources.

•Fossil fuels and many
minerals take millions of
years to form.

•They are being used up
faster than they can be
replenished by natural
processes.

•Solar energy, geothermal
energy, wind, water, and
air are renewable.

•Some resources, such as
solar energy, are
inexhaustible.

6. What happened to the number of red beans drawn during each

round?

The number of red beans relative to the white beans decreased with each round.

7. What would eventually happen to the red beans in the bag?

Eventually, the red beans will be entirely removed from the bag.

8. How would changing the number of beans drawn in each round make the

red beans last longer? Explain your answer.

With fewer total beans removed each round, consumption is reduced, and there are
more red beans available for each of the following rounds.

How long will natural resources be around?

Earth’s resources can be classified according to
how long supplies might last.

Renewable resources are resources that can
be replaced by natural processes in a relatively
short amount of time. Because they are
renewable, they will last a long time if used
wisely.

These resources come from natural processes
that have been happening for billions of years
and will continue to happen.

Renewable resources include air, water, living
things, and certain energy resources such as
solar, geothermal, wind, water, and biomass.

How long will natural resources be around?

Most energy in the United States comes from
nonrenewable resources.
Nonrenewable resources are natural resources that
are being used up faster than they can be replaced by
natural processes. Nonrenewable resources form slowly,
usually over millions of years.

If they are used faster than they form, they will run out.
Nonrenewable resources include fossil fuels, such as
coal, oil, natural gas, and minerals.

These resources are typically limited and nonrenewable
due to factors such as the long amounts of time
required for them to form or the environment in
which resources were created forming once or
only rarely in Earth’s history.
