The country boasts of a varying range of climatic regions that are as far apart as the Arctic conditions in the far corners of Alaska and the sub tropical climatic conditions in the state of Florida. The natural vegetation of the United States can also be as varied as tropical rain forests to arid desert scrubland, and its physical landscape can be as diverse as the high and rugged mountain peaks of the Appalachians and the flat expanses of the Prairie lowlands.

The flat, fertile prairie land of the Great Plains stretches to the west. The Rocky Mountains , at the western edge of the Great Plains, extend north to south across the continental United States, reaching altitudes higher than 14,000 feet (4,300 m) in Colorado .  The area to the west of the Rocky Mountains is dominated by the rocky Great Basin and deserts such as the Mojave . The Sierra Nevada range runs parallel to the Rockies, relatively close to the Pacific coast . At 20,320 feet (6,194 m), Alaska's Mount McKinley is the country's tallest peak. Active volcanoes are common throughout the Alexander and Aleutian Islands , and the entire state of Hawaii is built upon tropical volcanic islands. The supervolcano underlying Yellowstone National Park in the Rockies is the continent's largest volcanic feature.
