Geography of the United States

The term "United States", when used in the geographical sense, is the contiguous United States, the state of Alaska, the island state of Hawaii, the five

insular territories of Puerto Rico, Northern Mariana Islands, U.S. Virgin Islands, Guam,

and American Samoa, and minor outlying possessions. The United States shares land

borders with Canada and Mexico and maritime borders with Russia, Cuba, and the

Bahamas in addition to Canada and Mexico. The United States’ northern border with

Canada is the world's longest bi-national land border.

Climate

Due to its large size and wide range of geographic features, the United States contains examples of nearly every global climate. The climate is subtropical in the Southern United States, tropical in Hawaii and southern Florida, polar in Alaska, semiarid in the Great Plains west of the 100th meridian, Mediterranean in coastal California and arid in the Great Basin and the Southwest. Its comparatively favorable agricultural climate contributed (in part) to the

country's rise as a world power, with infrequent severe drought in the major agricultural regions, a general lack of widespread flooding, and a mainly temperate climate that receives adequate precipitation.

The main influence on U.S. weather is the polar jet stream which migrates northward into Canada in the summer months, and then southward into the USA in the winter months. The jet stream brings in large low pressure systems from the northern Pacific Ocean that enter the US mainland over the Pacific Northwest. The Cascade Range, Sierra Nevada, and Rocky

Mountains pick up most of the moisture from these systems as they move eastward. Greatly diminished by the time they reach the High Plains, much of the moisture has been sapped by the orographic effect as it is forced over several mountain ranges.

Agriculture is a major industry in the United States, which is a net exporter of food. As of the 2007 census of agriculture, there were 2.2 million farms, covering an area of 922 million acres (3,730,000 km²), an average of 418 acres (169 hectares) per farm. Although agricultural

activity occurs in every state in the union, it is particularly concentrated in the Great Plains, a vast expanse of flat, arable land in the center of the nation in the region around the Great Lakes known as the Corn Belt.

The U.S. was a leader in seed improvement i.e. hybridization and in expanding uses for crops from the work of George Washington Carver to the development of bioplastics and biofuels.

The mechanization of farming and intensive farming have been major themes in U.S. history, including John Deere's steel plow, Cyrus McCormick's mechanical reaper, Eli Whitney's cotton gin to the widespread success of the Fordson tractor and the combine harvesters first made from them. Modern agriculture in the U.S. ranges from the common hobby farms, small-scale producers to large commercial farming covering thousands of acres of cropland or rangeland.
