MBBS in USA



                         MBBS in USA
The United States of America (USA), commonly referred to as the United States (U.S.) or America, is a federal republic composed of 50 states, a federal district, five major self-governing territories, and various possessions. [fn 1] Forty-eight of the fifty states and the federal district are contiguous and located in North America between Canada and Mexico. The state of Alaska is in the far northwestern corner of North America, with a land border to the east with Canada and separated by the Bering Strait from Russia. The state of Hawaii is an archipelago in the mid-Pacific. The U.S. territories are scattered about the Pacific Ocean and the Caribbean Sea. Nine time zones are covered.
Climate
The climate of the United States varies due to differences in latitude, and a range of geographic features, including mountains and deserts. West of the 100th meridian, much of the US is semi-arid to arid, even desert in the far southwestern US. East of the 100th meridian, the climate is humid continental in the northern areas (locations above 40 north latitude), to humid temperate in the central and middle Atlantic coast regions, to humid subtropical climate in the Gulf and south Atlantic regions. The southern tip of Florida is tropical. Higher-elevation areas of the Rocky Mountains, the Wasatch and Bighorn mountain ranges, the Sierra Nevada, and the Cascade Range are alpine.
