The USA Geography
The USA is a Federal republic comprising 50
states and the District of Columbia. The USA is bounded by the Pacific Ocean on the west, Canada on the North, the Atlantic Ocean on the east and Mexico and the Gulf of Mexico on the South. The total area of the
USA is over 9 million km2. The
population equals 232 million people. The state originated with the declaration
of Independence of 1776. The national capital is
Washington, D. C.
continental part of the USA consists of 2 highland and 2 lowland
regions. The highland regions are the Appalachian Mountains in the east, and the Cordillera in the
west. The Appalachian Mountains run parallel to the Atlantic coast almost
from the Gulf of
Mexico into Canada. Their highest peak is 2,000 metres high.
The Cordillera stretches along the Pacific coast with the Sierra Nevada in the South and the Rocky Mountains continuing into Canada and Alaska in the North. The highest point in the USA is 6,197 metres in Alaska. Between the Cordillera and the Appalachian Mountains are the central lowlands, which are called
the prairie, and the eastern lowlands called the Mississippi valley.
The US has many thousands of streams. The Mississippi is one of the world's greatest
rivers. Its waters are gathered from 2/3 of the US. Together with its principal
tributary, the Missouri, it flows almost 4,000 miles from the Rocky Mountains to the Gulf of Mexico. One of its folk names is
"father of waters". The Ohio River and the Missouri River also rank among the most important rivers
of the world. The long Rio Grande forms most of the border between
the USA and Mexico. The Columbia River and its chief branch, the Snake River, the Sacramento River and the Colorado empty into the Pacific Ocean. The Yukon flows across Alaska to Bering Sea.
The USA has thousands of lakes of all kinds
and sizes. The Great Lakes make up the largest group of lake in the country and the greatest
collection of fresh water lakes in the world. Only Lake Michigan lies entirely inside the USA. Superior, Huron, Erie and Ontario form a border between the USA and Canada. There are also such great lakes as
Grassland and scrub dominate the
western half of the country, forest the eastern. Over 1/4 of the country is
still under forests. There are pines, walnut, oak, hickories. Fur-bearing
animals are muskrats, skunks and raccoons. Fish is an important natural
resource. Fishing provides an important industry on the Atlantic, Pacific, Gulf coasts and on the Great Lakes.
The US has large reserves of all the more
widely used minerals except tin. The minerals include coal, petroleum, nuclear
fuels, natural gas, iron copper, bauxite, lead, zinc, stone and many others.
