Where is the United States of America?

The United States of America is located in North America’s western hemisphere. It shares its border in the north with Canada, in the east with the Atlantic Ocean, in the south with Mexico and the Gulf of Mexico, and in the west with the Pacific Ocean. For more informational maps related to USA, check our Thematic Maps section.

The 49th state of the United States is Alaska, which is separated from the contiguous USA by Canada. It shares its boundary in the north with the Arctic Ocean and the Beaufort Sea, in the east by Canada, in the south by the Gulf of Alaska, Bering Sea, and the Pacific Ocean, in the west by the Arctic Ocean, Chukchi Sea, Bering Strait, and the Bering Sea.

The 50th state of the United States is Hawaii (located in the southwest of North America), which is located in Oceania. It is composed entirely of islands, which occupy most of an archipelago in the central Pacific Ocean. In Polynesia, it is the northernmost island group.

What is the Geography of the United States of America?

The United States of America (including 50 states as well as the District of Columbia) has a total area of 9,833,517 sq. km (3,796,742 sq. miles), out of which 9,147,593 sq. km (3,531,905 sq. miles) is land area and 685,924 sq. km (264836 sq. miles) is water area.

While the total land boundary of the USA is 12,048 km (7,486 miles), the coastline is 19,924 km (12,380 miles). Alaska is the largest state of the USA, spread across an area of 1,717,856.2 sq km (663,268 sq miles). Hawaii in the central Pacific region has an area of 28,311 sq km (10,931 sq miles).

The terrains of the USA include vast plain in the central part, mountains in the western USA, low mountains/hills in the eastern region, broad river valleys as well as rugged mountains in Alaska, and Hawaii’s rugged and volcanic topography.

While the highest point in North America is Mount McKinley’s Denali (6,190 m or 20,308 feet), the lowest point is Death Valley (86 m or 282 feet). The mean elevation is 760 meter or 2493 feet. Mountain ranges in the United States are Alaska Range, Saint Elias Mountains, Wrangell Mountains, Sierra Nevada, Sawatch Range, Cascade Range, and many more.

Some of the highest peaks are Denali, Mount Saint Elias, Mount Foraker, Mount Bona, Mount Blackburn, Mount Sanford, and others.

The major rivers of the USA are Mississippi River, Ohio River, Rio Grande River, Colorado River, and Hudson River. Thousands of lakes (natural and man-made) are there in the US. Some of the largest ones are Okeechobee, Iliamna, Lake of the Woods, Great Salt Lake, Ontario, Erie, Michigan, Huron, and Superior.

As the United States of America is a vast country, the climate varies from one place to the other. In general, the USA’s climate can be categorized as continental. Cold winters and hot summers characterize it. However, the duration of different seasons depends on the latitude as well as the distance from the sea.

The west coast’s climate is cold and damp in the northern part. In its southern region, the climate is the Mediterranean. In the case of the Gulf of Mexico’s coast, the winter is mild, and the summer is hot and muggy. In Florida, the climate is tropical. Therefore, the winter is cold, and the summer is cool-to-cold in the mountainous regions. The deserts in Florida have scorching hot summer and mild winter.

The United States experiences sudden cold waves in the winter season because of the cold air masses from Canada. This is because of the lack of obstacles between the two countries. When these cold spells take place in the winter, the temperature drops significantly below 0 °C or 32 °F. These spells can be intense and prolonged in the inland regions, the north-east, and the highlands.

Just like the cold spells, the heat waves during summer can be intense too, especially in the inland regions. 

While the western part of the US is more arid than the eastern regions, the north-central coast of the Pacific Ocean is predominantly rainy.

The western parts of the USA mainly have mountains, plateaus, and desert areas (vast and arid). The central-eastern part of the United States mostly has hills, low mountains, and flat earth. That’s why the climate is rainy and more humid. This area is vast, and that’s why the climatic differences are significantly different. Air masses clash in this part of the US, which makes the climate unstable and any meteorological phenomena (be it tornadoes, blizzards, hail, or storms) can be violent.

The air masses that come from Canada are generally dry and cold. However, as they pass over the Great Lakes, they pick up moisture. The air masses from the Gulf of Mexico are characterized as warm and moist. Higher temperature variations can be experienced in the Great Plains. However, in comparison to the East Coast, they are less humid and rainy, especially in the winter season.
