Coastline | 853 km | 19,924 km |
Maritime claims | territorial sea: 12 nm exclusive economic zone: 200 nm continental shelf: 200-m depth or to the depth of exploitation | territorial sea: 12 nm contiguous zone: 24 nm exclusive economic zone: 200 nm continental shelf: not specified |
Climate | varies; equatorial in south, tropical in center, arid in north | 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. |
Terrain | southern lowlands merge into central hills and plateaus; mountains in southeast, plains in north | 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 |
Elevation extremes | highest point: Chappal Waddi 2,419 m lowest point: Atlantic Ocean 0 m mean elevation: 380 m | 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 |
Natural resources | natural gas, petroleum, tin, iron ore, coal, limestone, niobium, lead, zinc, arable land | coal, copper, lead, molybdenum, phosphates, rare earth elements, uranium, bauxite, gold, iron, mercury, nickel, potash, silver, tungsten, zinc, petroleum, natural gas, timber, arable land; note 1: the US has the world's largest coal reserves with 491 billion short tons accounting for 27% of the world's total note 2: the US is reliant on foreign imports for 100% of its needs for the following strategic resources - Arsenic, Cesium, Fluorspar, Gallium, Graphite, Indium, Manganese, Niobium, Rare Earths, Rubidium, Scandium, Tantalum, Yttrium; see Appendix H: Strategic Materials for further details |
Land use | agricultural land: 78% (2018 est.) arable land: 37.3% (2018 est.) permanent crops: 7.4% (2018 est.) permanent pasture: 33.3% (2018 est.) forest: 9.5% (2018 est.) other: 12.5% (2018 est.) | agricultural land: 44.5% (2018 est.) arable land: 16.8% (2018 est.) permanent crops: 0.3% (2018 est.) permanent pasture: 27.4% (2018 est.) forest: 33.3% (2018 est.) other: 22.2% (2018 est.) |
Irrigated land | 2,930 sq km (2012) | 264,000 sq km (2012) |
Natural hazards | periodic droughts; flooding | 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" |
Environment - current issues | serious overpopulation and rapid urbanization have led to numerous environmental problems; urban air and water pollution; rapid deforestation; soil degradation; loss of arable land; oil pollution - water, air, and soil have suffered serious damage from oil spills | 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) |
Environment - international agreements | party to: Biodiversity, Climate Change, Climate Change-Kyoto Protocol, Climate Change-Paris Agreement, Comprehensive Nuclear Test Ban, Desertification, Endangered Species, Hazardous Wastes, Law of the Sea, Marine Dumping-London Convention, Marine Dumping-London Protocol, Marine Life Conservation, Nuclear Test Ban, Ozone Layer Protection, Ship Pollution, Wetlands signed, but not ratified: Tropical Timber 2006 | party to: Air Pollution, Air Pollution-Heavy Metals, Air Pollution-Multi-effect Protocol, Air Pollution-Nitrogen Oxides, Antarctic-Environmental Protection, Antarctic-Marine Living Resources, Antarctic Seals, Antarctic Treaty, Climate Change, Climate Change-Paris Agreement, Desertification, Endangered Species, Environmental Modification, Marine Dumping-London Convention, Marine Life Conservation, Nuclear Test Ban, Ozone Layer Protection, Ship Pollution, Tropical Timber 2006, Wetlands, Whaling signed, but not ratified: Air Pollution-Persistent Organic Pollutants, Air Pollution-Volatile Organic Compounds, Biodiversity, Climate Change-Kyoto Protocol, Comprehensive Nuclear Test Ban, Hazardous Wastes, Marine Dumping-London Protocol |
Geography - note | the Niger River enters the country in the northwest and flows southward through tropical rain forests and swamps to its delta in the Gulf of Guinea | 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 |
Total renewable water resources | 286.2 billion cubic meters (2017 est.) | 3.069 trillion cubic meters (2017 est.) |
Population distribution | largest population of any African nation; significant population clusters are scattered throughout the country, with the highest density areas being in the south and southwest as shown in this population distribution map | 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 |
