Much of Florida is situated on a peninsula between the Gulf of Mexico, the Atlantic Ocean, and the Straits of Florida. Its geography is marked by a coastline, by the omnipresence of 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 to border both the Gulf of Mexico and the Atlantic Ocean. Much of the state is at or near sea level and its terrain is characterized by sedimentary soils. The climate varies from subtropical in the north to tropical in the south. Its symbolic animals like the American alligator, Florida panther and the manatee, can be found in the Everglades, one of the most famous national parks in the world.
