INTRODUCTION
Geography in translation from Greek means earth description. It is the study of the location and distribution of living things and the earth features among which they live.
One of the main tasks of geography is to identify and record the location of places, of earth features and of human population and activities. But it is not enough to know only the location of a place, it is also important to know the kinds of people who live there, landform, climate and types of animals and plants that are found there.
The earths surface changes constantly. Some changes result from natural forces, such as the erosion or the ocean currents that alter coastline. At times, human activities and natural processes combine to cause changes on the earth surface.
It is important to study such processes in order to discover how landscapes developed in the past and how they will change in future. Geographical position of the country, land features, climate affect different sides of peoples life: history, economy, distribution of the population and even national character. And from the point of view of geopolitics even political organization of the society is determined partly by the geographical position of the country. For example, the United States occupies a favourable geographical position. The Atlantic and the Pacific oceans are of great importance for the countrys sea communications with Europe, Africa and South America.
The United States of America is a country of great contrasts and similarities. The diversity of the country stems from the fact that it is so large and has so many kinds of land, climate and people. It is impossible to generalize about the weather, the landscape, or even the way of living because the nation occupies nearly half of the continent.
The aim of this course paper is to provide information about geography and environment of the USA, but not only about landforms or climate but the human imprint on the landscape.
In fact, physical...
CONCLUSION
In this course paper the following questions have been studied: the geographical position of the USA, physical features of the land, climate, main rivers and lakes, main environmental problems.
The United States is the nearest thing to an instant geography lesson that the world can offer. It is blessed with a wealth of natural beauty. The land of the country is as varied as it is vast. The physical features of the United States are greatly diverse. There are high mountains and the flattest of prairies, tropical heat and arctic cold, fertile valleys and desert areas. All sorts of products are grown, there are industries of every kind. The most densely and the most sparsely populated areas of the world are to be found in the United States.
The United States has many kinds of climate. The weather ranges from the warm, wet conditions of the Appalachians to the desert conditions of some of the weste
states. It varies from almost winterless climates in southe
Arizona and southe
Florida to long, very cold winters in Montana, North Dakota and South Dakota. In other words, the United States has practically all the climatic zones. With every variation of surface it possesses every variety of climate, from that of the tropics (Hawaii), to that of the Arctic regions (Alaska).
The greatest rivers of the USA are the Mississippi, which flows into the Gulf of Mexico, the Colorado and the Columbia, which flow into the Pacific Ocean, the Saint Lawrence River and the Hudson River, which flow into the Atlantic Ocean. The USA has thousands of lakes of all kinds and sizes. Lake Michigan, Superior, Huron, Erie, Ontario and the Great Salt Lake are the most important of them.
Each region of the United States has characteristics of its own. Within this course paper, regions have been presented largely as though they are distinct territorially. An examination of the regions indicates a subdivision that should be generally recognizable. Several of the regions closely follow...
