This allowed the US to grow and become strong with little outside interference. - And today the development of means of communication and transportation makes the U.S. well connected to the rest of the world. Size of the US -a land area of 9.3 million square kilometers. - stretches 2,575 kilometers from north to south and 4,500 kilometers from east to west. - the 4th largest country in the world in size after Russia, Canada and China. -All together there are 50 states in the US. -Of all the states Alaska is the largest in area and Rhode Island the smallest. -on the mainland Texas is the largest. 2. topography: Mountains in U. S. A. Appalachian Mountains 阿巴拉契亚山脉 Rocky Mountains 落基山脉 The Appalachian Mountains -run slightly from the northeast to southwest -old (have been worn out over millions of years) and low (the highest peak is only a little over 2,000 metres) -noted for virgin forests and mines -served as a natural barrier for westward movement during the early settlement. The Appalachian Mountains the great mountain system of eastern North America; one sixth of the national territory on the continent; From province of Quebec in Canada to Northern Alabama.
