The Unires States of America is the word s fourth largest country. Only Russia< Canada and China have bigger territories than the US. There are fifty states in the country. Forty-eight are in the same part of North America. The other two are Alaska in the north, and Hawaii situated on eight islands in the Pacific.
The United States stretches from the Pacific Ocean to the Atlantic Ocean, which wash the country in the west and in the east. Long mountain chains run down the Pacific coast. In this part of the country is Death Valley, the lowest place in North and South Americas. Here, too, is the Grand Canyon which the Colorado River made millions of years ago. In some places it is about 6 km deep. Farther east lie the tall peaks of the Rocky Mountains that run from Canada to Mexico. Beyond them stretch the Great Plains where the mighty Mississippi River flows. Annother mountain chain, the Appalachians, runs down the eastern part of the United States. The USA borders on Canada in the north, where the five Great Lakes are situated, and Mexico in the South.
