Florida is a state in the southeastern region of the United States, bordered to the west by the Gulf of Mexico, to the north by Alabama and Georgia, to the east by the Atlantic Ocean, and to the south by the Straits of Florida. Florida is the 22nd most extensive, the 4th most populous, and the 8th most densely populated of the 50 United States. The state capital is Tallahassee, the largest city is Jacksonville, and the largest metropolitan area is the Miami metropolitan area.
Much of Florida is a peninsula between the Gulf of Mexico, the Atlantic Ocean, and the Straits of Florida. Its geography is notable for a coastline, omnipresent water and the threat of hurricanes. Florida has the longest coastline in the contiguous United States, encompassing approximately 1,350 miles (2,170 km), and is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. Much of the state is at or near sea level and is characterized by sedimentary soil.
