paragraph_text: The Gulf of Mexico (Spanish: Golfo de México) is an oceanic basin and a marginal sea of the Atlantic Ocean, mostly surrounded by the North American continent. It is bounded on the northeast, north, and northwest by the Gulf Coast of the United States; on the southwest and south by the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo; and on the southeast by Cuba. The coastal areas along the Southern U.S. states of Texas, Louisiana, Mississippi, Alabama, and Florida, which border the Gulf on the north, are occasionally referred to as the " Third Coast " of the United States (in addition to its Atlantic and Pacific coasts), but more often as "the Gulf Coast".
  
  The Gulf of Mexico took shape about 300 million years ago (mya) as a result of plate tectonics. The Gulf of Mexico basin is roughly oval and is about 810 nautical miles (1,500 kilometers; 930 miles) wide. Its floor consists of sedimentary rocks and recent sediments. It is connected to part of the Atlantic Ocean through the Straits of Florida between the U.S. and Cuba, and with the Caribbean Sea via the Yucatán Channel between Mexico and Cuba. Because of its narrow connection to the Atlantic Ocean, the gulf has very small tidal ranges.
  
  The size of the gulf basin is about 1.6 million square kilometers (620,000 square miles). Almost half of the basin consists of shallow continental shelf waters. The volume of water in the basin is roughly 2.4 million cubic kilometers (580 thousand cubic miles). The gulf is one of the most important offshore petroleum production regions in the world, making up 14% of the United States' total production. Moisture from the Gulf of Mexico also contributes to weather across the United States, including severe weather in Tornado Alley.
