The biggest peninsulas are the Florida Peninsula and Alaska. The United States of America has got three neighbours Mexico in the south, Canada in the north and the world's biggest country Russia just across the Bering Strait. Relief The continental part of the USA consists of two highland and two lowland regions. The highland regions are the Appalachians in the east and the Cordilleras in the west. The Appalachians run parallel to the Atlantic coast from the Gulf of Mexico to Canada; the highest peak is 2000 m high. The Cordilleras run along the Pacific coast with the Sierra Nevada in the south and the Rocky Mountains in the north; the highest peak is Mt. Whitney (4,540 m) in the Sierra Nevada. The Cordilleras are still an active region of the Earth. There are a number of active volcanoes there and often earthquakes shake the land.
The state of Alaska is separated from the rest of the U.S.A. by Canada. Hawaii, which became the fiftieth state in 1959, is in the Pacific Ocean, halfway between the continents of America and Asia. The area of the United States of America is over nine million square kilometres. The continental part of the U.S.A. consists of two highland regions and two lowland regions. The highland regions are the Appalachian Mountains in the east and the Cordilleras in the west. The Appalachian Mountains run parallel to the Atlantic coast almost from the Gulf of Mexico into Canada. The highest peak is 2000 metres high. The Cordilleras stretch along the Pacific coast with the Sierra Nevada in the south and the Rocky mountains continuing into Canada and Alaska in the north. Their highest point in the U.S.A. is 4540 metres in Sierra Nevada. The five Great lakes, between U.S.A. and Canada, are joined together by short rivers or canals
The mountain ranges in the west and in the east of the country prevent damp air from moving into inland. As there are no mountains running from east to west, cold polar air masses can move far to the south. Sometimes warm tropical air from the south reaches far to the north. Hot winds blowing from the Gulf of Mexico often bring hurricanes. The summers are warm and the winters are cold in the central part of the country.The rainfall is heavier on the western slopes of the Cordilleras, the eastern and the south-eastern parts of the country get a lot of rain too. It rains less in the area of the Great Plains. The western coast is much warmer than the eastern coast because of the influence of the Pacific Ocean. . Geography The main part of United States extends from Atlantic Ocean in the east to the Pacific Ocean in the west.It covers the middle of the North American continent.This
Lowland. The Appalachian Mountains are old and worn down. West of the Appalachians stretch the Central Plains, the Great Plains, and the Mexican Lowland. The Central Plains are 500-400 m high and have a hilly relief in the north. The Great Plains are a deeply cut plateau with the heights of 500 m in the east to 1600 m in the west. The flat Mexican Lowland, with the height of up to 150 m, is swampy along the Gulf coast and surrounded by a strip of marshes. The Cordilleras consist of rows of mountain ranges with the heights of up to 3000-5000 m. In Alaska the mountain ranges stretch in the west-east direction. 4 On the territory of the USA the mountain ranges stretch in the north-south direction. The first from the east are the Rocky Mountains. West of the Rockies lie vast plateaus and tablelands: the volcanic Columbia Plateau, the Great Basin, the Colorado Plateau.
