| Climate | mostly temperate, but tropical in Hawaii and Florida, arctic in Alaska, semiarid in the great plains west of the Mississippi River, and arid in the Great Basin of the southwest; low winter temperatures in the northwest are ameliorated occasionally in January and February by warm chinook winds from the eastern slopes of the Rocky Mountains note: many consider Denali, the highest peak in the US, to be the world's coldest mountain because of its combination of high elevation and its subarctic location at 63 degrees north latitude; permanent snow and ice cover over 75 percent of the mountain, and enormous glaciers, up to 45 miles long and 3,700 feet thick, spider out from its base in every direction; it is home to some of the world's coldest and most violent weather, where winds of over 150 miles per hour and temperatures of -93°F have been recorded. | extremely diverse; tropical in south to subarctic in north |
| Terrain | vast central plain, mountains in west, hills and low mountains in east; rugged mountains and broad river valleys in Alaska; rugged, volcanic topography in Hawaii | mostly mountains, high plateaus, deserts in west; plains, deltas, and hills in east |
| Elevation extremes | highest point: Denali 6,190 m (Mount McKinley) (highest point in North America) lowest point: Death Valley (lowest point in North America) -86 m mean elevation: 760 m note: Denali is one of the most striking features on the entire planet; at 20,310 feet, it is the crowning peak of the Alaska Range and the highest mountain on North America; it towers three and one-half vertical miles above its base, making it a mile taller from base to summit than Mt. Everest; Denali's base sits at about 2,000 feet above sea level and rises over three and one-half miles to its 20,310 foot summit; Everest begins on a 14,000-foot high plain, then summits at 29,028 feet. note: the peak of Mauna Kea (4,207 m above sea level) on the island of Hawaii rises about 10,200 m above the Pacific Ocean floor; by this measurement, it is the world's tallest mountain - higher than Mount Everest (8,850 m), which is recognized as the tallest mountain above sea level | highest point: Mount Everest (highest peak in Asia and highest point on earth above sea level) 8,849 m lowest point: Turpan Pendi -154 m mean elevation: 1,840 m |

| Irrigated land | 264,000 sq km (2012) | 690,070 sq km (2012) |
| Natural hazards | tsunamis; volcanoes; earthquake activity around Pacific Basin; hurricanes along the Atlantic and Gulf of Mexico coasts; tornadoes in the Midwest and Southeast; mud slides in California; forest fires in the west; flooding; permafrost in northern Alaska, a major impediment to development volcanism: volcanic activity in the Hawaiian Islands, Western Alaska, the Pacific Northwest, and in the Northern Mariana Islands; both Mauna Loa (4,170 m) in Hawaii and Mount Rainier (4,392 m) in Washington have been deemed Decade Volcanoes by the International Association of Volcanology and Chemistry of the Earth's Interior, worthy of study due to their explosive history and close proximity to human populations; Pavlof (2,519 m) is the most active volcano in Alaska's Aleutian Arc and poses a significant threat to air travel since the area constitutes a major flight path between North America and East Asia; St. Helens (2,549 m), famous for the devastating 1980 eruption, remains active today; numerous other historically active volcanoes exist, mostly concentrated in the Aleutian arc and Hawaii; they include: in Alaska: Aniakchak, Augustine, Chiginagak, Fourpeaked, Iliamna, Katmai, Kupreanof, Martin, Novarupta, Redoubt, Spurr, Wrangell, Trident, Ugashik-Peulik, Ukinrek Maars, Veniaminof; in Hawaii: Haleakala, Kilauea, Loihi; in the Northern Mariana Islands: Anatahan; and in the Pacific Northwest: Mount Baker, Mount Hood; see note 2 under "Geography - note" | frequent typhoons (about five per year along southern and eastern coasts); damaging floods; tsunamis; earthquakes; droughts; land subsidence volcanism: China contains some historically active volcanoes including Changbaishan (also known as Baitoushan, Baegdu, or P'aektu-san), Hainan Dao, and Kunlun although most have been relatively inactive in recent centuries |
| Environment - current issues | air pollution; large emitter of carbon dioxide from the burning of fossil fuels; water pollution from runoff of pesticides and fertilizers; limited natural freshwater resources in much of the western part of the country require careful management; deforestation; mining; desertification; species conservation; invasive species (the Hawaiian Islands are particularly vulnerable) | air pollution (greenhouse gases, sulfur dioxide particulates) from reliance on coal produces acid rain; China is the world's largest single emitter of carbon dioxide from the burning of fossil fuels; water shortages, particularly in the north; water pollution from untreated wastes; coastal destruction due to land reclamation, industrial development, and aquaculture; deforestation and habitat destruction; poor land management leads to soil erosion, landslides, floods, droughts, dust storms, and desertification; trade in endangered species |

| Geography - note | note 1: world's third-largest country by size (after Russia and Canada) and by population (after China and India); Denali (Mt. McKinley) is the highest point (6,190 m) in North America and Death Valley the lowest point (-86 m) on the continent note 2: the western coast of the United States and southern coast of Alaska lie along the Ring of Fire, a belt of active volcanoes and earthquake epicenters bordering the Pacific Ocean; up to 90% of the world's earthquakes and some 75% of the world's volcanoes occur within the Ring of Fire note 3: the Aleutian Islands are a chain of volcanic islands that divide the Bering Sea (north) from the main Pacific Ocean (south); they extend about 1,800 km westward from the Alaskan Peninsula; the archipelago consists of 14 larger islands, 55 smaller islands, and hundreds of islets; there are 41 active volcanoes on the islands, which together form a large northern section of the Ring of Fire | note 1: world's fourth largest country (after Russia, Canada, and US) and largest country situated entirely in Asia; Mount Everest on the border with Nepal is the world's tallest peak above sea level note 2: the largest cave chamber in the world is the Miao Room, in the Gebihe cave system at China's Ziyun Getu He Chuandong National Park, which encloses some 10.78 million cu m (380.7 million cu ft) of volume note 3: China appears to have been the center of domestication for two of the world's leading cereal crops: millet in the north along the Yellow River and rice in the south along the lower or middle Yangtze River |
| Total renewable water resources | 3.069 trillion cubic meters (2017 est.) | 2,840,220,000,000 cubic meters (2017 est.) |
| Population distribution | large urban clusters are spread throughout the eastern half of the US (particularly the Great Lakes area, northeast, east, and southeast) and the western tier states; mountainous areas, principally the Rocky Mountains and Appalachian chain, deserts in the southwest, the dense boreal forests in the extreme north, and the central prarie states are less densely populated; Alaska's population is concentrated along its southern coast - with particular emphasis on the city of Anchorage - and Hawaii's is centered on the island of Oahu | overwhelming majority of the population is found in the eastern half of the country; the west, with its vast mountainous and desert areas, remains sparsely populated; though ranked first in the world in total population, overall density is less than that of many other countries in Asia and Europe; high population density is found along the Yangtze and Yellow River valleys, the Xi Jiang River delta, the Sichuan Basin (around Chengdu), in and around Beijing, and the industrial area around Shenyang |
