The physical map of the USA is a complex and diverse representation of the country's geography. The United States of America is the third-largest country in the world, covering an area of approximately 3.8 million square miles. It is bounded by the Atlantic Ocean to the east, the Pacific Ocean to the west, Canada to the north, and Mexico to the south. The country's physical features include mountains, rivers, deserts, and coastlines, which have played a significant role in shaping its history, culture, and economy.
Mountain Ranges
The USA is home to several major mountain ranges, including the Rocky Mountains, the Appalachian Mountains, and the Sierra Nevada. The Rocky Mountains stretch from British Columbia, Canada, to New Mexico, covering a distance of over 3,000 miles. The highest peak in the Rockies is Mount Elbert, located in Colorado, which stands at an elevation of 14,433 feet. The Appalachian Mountains, on the other hand, are an old and eroded range that stretches from Quebec, Canada, to Alabama, covering a distance of over 2,400 miles. The Sierra Nevada mountain range is located in the western United States and is home to Yosemite National Park, Lake Tahoe, and Mount Whitney, the highest peak in the contiguous United States.
Major Rivers
The USA has an extensive network of rivers that have played a crucial role in the country’s development. The Mississippi River is one of the longest and most iconic rivers in the United States, stretching over 2,300 miles from its source in Lake Itasca, Minnesota, to the Gulf of Mexico. Other major rivers include the Colorado River, the Rio Grande, and the Columbia River. The Colorado River is a vital source of water and hydroelectric power, flowing through the Grand Canyon and into the Gulf of California. The Rio Grande forms the border between the United States and Mexico, while the Columbia River forms the border between the states of Washington and Oregon.

| Sierra Nevada | Western United States | Mount Whitney (14,505 ft) |
Deserts and Coastlines
The USA is home to several major deserts, including the Mojave Desert, the Sonoran Desert, and the Great Basin Desert. The Mojave Desert is the smallest and driest of the four major deserts in North America, covering an area of approximately 50,000 square miles. The Sonoran Desert is the largest desert in North America, covering an area of over 100,000 square miles. The Great Basin Desert is a cold desert that covers an area of over 190,000 square miles, stretching from the Sierra Nevada to the Rocky Mountains.
Coastal Regions
The USA has a diverse range of coastal regions, including the Atlantic Coast, the Pacific Coast, and the Gulf Coast. The Atlantic Coast is home to several major cities, including New York City, Boston, and Miami. The Pacific Coast is known for its natural beauty, with iconic landmarks like Big Sur, Monterey, and the Golden Gate Bridge. The Gulf Coast is a vital region for the country’s oil and gas industry, with major ports like Houston and New Orleans.
