The United States of America is the fourth largest country in the world (after
Russia, Canada and China). It occupies the southern part of North America and
stretches from the Pacific to the Atlantic Ocean. It also includes Alaska in the north
and Hawaii in the Pacific Ocean. The total area of the country is about nine and a
half million square kilometers. The USA borders on Canada in the north and on
Mexico in the south. It also has a sea-boarder with Russia.
The USA is made up of 50 states and the District of Columbia, a special
federal area where the capital of the country, Washington, is situated. The
population of the country is more than 270 million.
If we look at the map of the USA, we can see lowlands and mountains. The
highest mountains are the Rocky Mountains, the Cordillera and the Sierra Nevada.
The highest peak is Mount McKinley which is located in Alaska.
America's largest rivers are the Mississippi, the Missouri, the Rio Grande
and the Columbia. The Great Lakes on the border with Canada are the largest and
deepest in the USA.
The climate of the country varies greatly. The coldest regions are in the
north. The climate of Alaska is arctic. The climate of the central part is continental.
The south has a subtropical climate. Hot winds blowing from the Gulf of Mexico
often bring typhoons. The climate along the Pacific coast is much warmer than that
of the Atlantic coast.
The USA is a highly developed industrial country. It's the world's leading
producer of copper and oil and the world's second producer of iron ore and coal.
Among the most important manufacturing industries are aircraft, cars, textiles,
radio and television sets, armaments, furniture and paper.
Though mainly European and African in origin, Americans are made up
from nearly all races and nations, including Chinese and native Americans.
