[08:25.53]If you look at an atlas,you will see that the United States of America
[08:33.76]is located on the North American continent
[08:37.31]between thirty and fifty degrees north latitude.
[08:41.15]It extends about two thousand five hundred miles from east to west
[08:41.20]and about twelve hundred miles from north to south.
[08:45.28]The western third of the country consists mainly of a high plateau
[08:51.42]broken by numerous mountain ranges,the chief of which are the Rocky Mountains
[08:57.06]located near the western edge of the high ground.
[09:01.63]To the east of this region lie the Great Plains.
[09:05.29]This is a region of very flat ground extending from the Canadian border
[09:10.64]to the Gulf of Mexico,and eastward as far as the Appalachian Mountians
[09:16.18]The Appalachians are a range of low mountains and hills running parallel to the Atlantic coast
[09:24.02]and about one to two hundred miles inland.
[09:27.54]Along the center of the Great Plains,
[09:31.20]flowing south from the Canadian border to the Gulf of Mexico,is the Mississippi River.
[09:37.23]This river,together with the Missouriand the Arkansas
[09:41.47]which join it from the west and the Ohio which joins it from the east
[09:46.27]forms the central river system of the United States.
[09:50.35]In the north are five great lakes
[09:54.19]which empty into the Atlantic Ocean through the St,Lawrence River
[09:58.39]The Colorado River in the southwest and the Columbia in the northwest
[10:04.45]are the other principal rivers of the country.
[10:08.82]The climate of the country is similar to that of other large continental areas
[10:14.07]in the temperate zone.
[10:15.87]It is very warm in the summer and all of it,
[10:19.29]except the South,is cold in the winter.The West,
[10:24.54]and especially the Southwest,is very dry and some areas are desert
[10:30.26]Florida,a peninsula in the southeast has a semitropical climate.
[10:37.03]The country is divided into four time zones
[10:41.36]The Eastern zone includes the coast and the Appalachian Mountains.
[10:46.72]he Central zone covers the plains area.
[10:46.79]The Mountain zone takes in most of the mountainous area
[10:51.23]and the Pacific zone covers the Pacific coast
