United States Geography
Transcript of United States Geography
In the south, the beaches are sandy, and the weather is hot. When you go north, the beaches are rocky, and the weather is colder. The Pacific Ocean
on the U.S.A.'s West Coast is always chilly!
The West Coast / Pacific Coast
Alaska is the largest state in the U.S.A. Mt. McKinley, the tallest mountain in North America, is there. Alaska is so far north that some parts are past the Arctic Circle. This means that in summer, the sun never sets, and in winter, the sun never rises. Alaska's coldest temperature ever was -80 F (-62 C). Even though Alaska's winters are cold and dark, the people are lucky because they get to see the Northern Lights.
The southwest of the U.S.A. is very dry. It
doesn't rain very much, and there are many deserts. The land is also very high. The average elevation is 5,000 feet or 1,500 meters. This makes the weather hot in the daytime and cold at night.
The Rocky Mountains
The Rockies are a mountain range. (That means there are many mountains in a line.) The Rockies are 3,000 miles long and divide the U.S.A. from north to south.
The middle of the
U.S.A. is flat. The
land is great for
growing food. Many farms grow wheat and corn. The Midwest's nickname is America's 'breadbasket'.
The Mississippi River
The Mississippi River is 2,500 miles long. It flows north to south through the Midwest giving water to all the farms.
The Midwest's biggest
problem is tornadoes.
When cold air from
the Rockies meets the warm air from the ocean, the air twists together. The wind in a tornado can blow 300 miles per hour!
The South is hot and wet. This makes the weather very humid. There are many rivers in the South, so it is a good place to grow rice and cotton. Sometimes rivers flow through a forest. These are called swamps or bayous.
The Appalachian Mountains
mountain range in
eastern U.S.A. They are 1,500 miles long from north to south.
the Rockies, the
Appalachians have many tall rolling hills.
The East Coast / Atlantic Coast
Most of the beaches on the East Coast are flat and sandy. The summers are warmer and the winters are colder than the West Coast. The Atlantic Ocean on the U.S.A.'s East Coast is warmer than the Pacific Ocean.
Hurricanes come to the East Coast because this part of the Atlantic Ocean is warm. Strong winds and heavy rain can be very dangerous.
The U.S.-Mexico border is almost 2,000 miles long.
The east half is a natural border that follows the Rio Grande River.
The west half is a
geometric border. The
U.S built a giant wall
from the Pacific Ocean
to the Rio Grande River.
are the lines that tell where a country stops. Sometimes mountains or rivers make natural borders that tell where two countries meet. Other times, there is only a line on a map. These are called geometric borders.
The U.S.-Canada border is over 5,000 miles long.
Some lakes and rivers form natural borders between Canada and the U.S. However, it is mostly a geometric border following the 49th parallel and 141st meridian. The geometric
parts of the border are very straight lines. The
U.S.A. and Canada drew lines on the ground or
cut lines through forests to show where the
two countries meet.
Hawaii was the last (50th) state
to become part of the U.S.A.
The state is actually a chain of hundreds of islands in the Pacific Ocean with eight main islands. Hawaii is warm all year and has great beaches.
The United States of America
With all 50 states put together, America is the 3rd largest country in the world.
