USA – geography, weather, climate, population, places of interest

The USA is situated in southern part of North America. Its neighbours are Canada on north and Mexico on south. East of the USA is the Atlantic Ocean and west the Pacific. South-east the american shore is washed by the Gulf of Mexico. The east coast is touched by the Labrador Stream that is cold as the California Stream is. The largest american state is Alaska, which to the north-west. Also the Hawaiian Islands belong to the USA. They are situated in the Pacific Ocean, south-west of California.

On the eastern coast there are the Appalachian Mountains. These are geologically the oldest. The highest mountain is Mt. Mitchell. West of the Appalachian Highlands there is the Mississippi River which is probably the most famous american river, first of all thanks to Mark Twain and his Huckleberry Finn. Its name is probably of indian origin and means "great water."

Probably half of the USA is made by the Cordilleras in the west. On the shore there are the Coast Mountains. Inland there are the Rocky Mountains which are higher than 4000 m.

In the north on the border with Canada there are the Niagara Falls and the five Great Lakes - Lake Ontario, Lake Erie, Lake Michigan, Lake Huron and Lake Superior. They are the largest natural basin of fresh water in the world. The biggest river of Alaska is the Yukon which is often ice-bound. Another big river is the Missouri. It is a tributary of the Mississippi. The Rio Grande river is a natural border between Texas and Mexico. Famous Great Canyon can be found on the Colorado River.

The United States has got many kinds of climate. From Arctic in Alaska to subtropic in Florida. The majority of the area of the USA has got a temperate climate. But we can divide it into four regions. The Atlantic Coast is relatively cold, occasionally with heavy snowfalls in winter. The Central Plains have got very humid summers and cold winters with strong winds. In the west there are cold winters and hot dry summers. The weather in the north often differs from that in the south. The Death Valley in California is about the hottest place on earth in summer. California, Arizona, New Mexico and Florida belong to the so-called Sun Belt States. The Middle West winters are cold and long. But the summers are very hot and we can find deserts and semi-deserts here. East of the Mississippi river and south of the Great Plains cold and warm streams often meet there. So, in this area there are often tornados. The terrible frost is in Montana or in Alaska. The Hawaiian Islands have got a very pleasant and warm climate. There are minimal differences between summers and winters.

Owing to the different climate, the plant kingdom is also various. Deep forests are still in the Appalachian Mountains, in the Cordilleras and on the pacific shore. In the west part of the Central Plains there are prairie used for agriculture or as grassland. Inside of the Cordilleras there are some kinds of semi-desert flora. In Alaska there is diverse flora. We can find some kinds of moss and lichen there. In the Hawaii the flora is typically tropic.
