Trang 3What is a natural resource?
Nature is truly amazing Just take a look around
you Almost everything you see started out as a
natural resource Natural resources are useful
materials that come from the earth
The toothpaste you used this morning contains sand
Sand is a natural resource The paper this book was
printed on came from a tree Our forests are natural
resources The gasoline that powers the car or the bus
you ride in started out as oil Oil is a natural resource
How about cars? Cars are made from natural
resources too Car bodies are formed from sheets of
steel Steel is made mostly of iron, which is found in
rock Iron is an important natural resource
Trees are a natural resource.

Five Regions in One Country
The United States is the fourth-largest country in the world It is big enough to be divided into five
different regions A region is a large land area that
has special features
The five regions of the United States have very
different physical environments You can tell one
type of physical environment from another by
observing its landforms and its climate Landform
is a scientific word for the different shapes found
on Earth’s surface Deserts and mountains are two examples of landforms Climate refers to the kind of weather a place has from year to year
This map shows the five regions of the United States
Northeast region
Southeast region Southwest region
West region
Midwest region
Trang 4The five regions of the United States look very
different You will find mountains in the West and
flat plains in the Midwest The Southwest is very
hot and dry all year round The Northeast can get
very cold and snowy during the winter The South is
warmer than some other regions
This is a hot, dry climate in
the Southwest region.

Did you know that the first
letters of the four directions on
a map—North, East, West, and
South—spell the word NEWS?

Where is that from?
Natural resources come from nature The five regions of the United States have very different resources in their soil, rocks, and waters Let’s look at
a few states and their natural resources
Texas is a very large state in the Southwest It is famous for its oil Oil is a natural resource that is found beneath the ground It comes from wells, or
deep holes in Earth’s surface We use oil for fuel Fuels
provide us with heat, light, and other forms of energy
This is an oil well.
Trang 5The state of Wisconsin is in our nation’s Midwest
This state has lots of cows, farmland, and trees
Wisconsin is known for its dairy products, such as milk
and cheese This state also produces the most paper
in our country
Idaho is a state in the Northwest Much of its land
is used for farming Idaho is famous throughout the
world for its plentiful potato crops The soil in Idaho is
good for growing wheat and trees
Midwestern states, such as Wisconsin, have cows and livestock.
You probably already know how valuable our forests are They provide homes for animals and oxygen for
us to breathe They shade us from the Sun
Trees are also important to the building industry
Lumber comes from trees It is wood that has been cut into boards Wood from trees is also used to make paper and furniture
You might be surprised at some of the other things that are made from trees Medicines, fabrics, bowling balls, football helmets, hairspray, paints, tires, cough drops, and gum all come from trees
The best thing about trees, though, is that they
can be replaced by planting new ones That makes them a renewable resource If we are careful, they will
never disappear!
Many potato crops are grown
in Idaho.
Trang 6Gold is a very valuable mineral A mineral is a
natural resource that has never been alive Gold
was first discovered in California back in 1848 This
discovery caused thousands of people to move out
west The big westward movement became known as
the Gold Rush
Can you dig it?
Gold is usually found buried in rock Sometimes it is
mixed with loose soil People panned for gold in the
Old West by swirling water from muddy streams in
pans to help separate the tiny gold flecks from the dirt
Later, people dug deep holes called gold mines
in the earth to search for larger chunks of gold A
miner’s job was to get the nuggets, or chunks of gold,
out of the mine
Thousands of people headed west hoping
to find gold nuggets such as these.
9
Many of the people who took part in the Gold Rush wanted to find some gold for themselves Others followed the crowd looking for different kinds of work
Let’s see what might have happened out west in
1849 after gold was discovered Many people traveled far to look for gold, but there were other jobs to do
The Miner Forty-Niners
The gold miners were nicknamed “forty-niners”
because the busiest year for gold mining in California was 1849 Between the discovery of gold
in 1848 and the end of the Gold Rush in 1850, about eighty thousand people moved to California
Miners panned for gold
Trang 7The miners had to buy supplies, so some people set
up stores to sell things The miners had to eat, so other
people grew food, cooked, or set up places for miners
to buy meals The miners might get injured or sick, so
doctors were needed People were able to find many
things to do even if they were not looking for gold!
Some mines were in
the mountains.
10
Then what happened?
Not many gold miners got rich By 1850 the Gold Rush was over A lot of miners decided to go back to the states they came from Some of the mining towns were deserted They became known as “ghost towns”
after everyone left
Some people ended up staying in the area, though
Many of them took up farming and communities
were formed A community is a place where people live, work, and have fun together California became this country’s thirty-first state at the end of 1850

Trang 8How did fuels get under
the ground?
Oil, coal, and natural gas are fuels We burn them to
produce heat, electricity, and other forms of energy
All of these fuels were formed millions of years ago
and are buried in the ground
You are probably wondering how all that oil, coal,
and natural gas ended up getting stuck under tons
of rock
Let’s take a look at how oil forms Coal and natural
gas form almost the same way
Oil is sometimes called
“black gold” because it is such
a valuable natural resource.
Trang 9How Oil Is Formed
Suppose it is three hundred million years ago, even
before the dinosaurs roamed Earth Billions of tiny
plants and animals were living in Earth’s oceans
When these ocean creatures died and sank to the
bottom of the water, they formed a muddy layer Over
time, the plant and animal bodies were buried under
more and more layers of mud It got pretty hot under
there, and the mud turned to rock Much later, those
dead plants and animals turned into thick, gooey oil
1859
America’s first oil field is drilled in Pennsylvania
1930s
Lots of oil is found
in Texas.
1839
The first steam shovel
is invented This invention makes it much easier to dig coal from the ground.
A Fuel Time Line

Will our natural resources last forever?
Not every natural resource is like a tree After a tree
is cut down, a new one can be planted in its place
That is why forests are called renewable resources!
Unfortunately, oil, coal, and natural gas are not like that Once we find and use all the oil, coal, and natural gas in Earth’s crust, they will be gone forever
We cannot “plant” new supplies That is why it is so important to conserve our resources
1973
The price of oil goes way up
in the United States People have to wait in lines for hours at gas stations to fill
up their gas tanks.
2004
Scientists predict that plankton, sunflowers, and bananas may be the fuels of the future.
1997
The gas-electric hybrid car is introduced in Japan It can run
on gas or electricity.
