Florida and Texas were granted statehood in 1845, and the admission of Texas led to war with Mexico. Gulf of Mexico hurricanes, especially some in recent years such as Katrina, are famous for their potential for heavy damage and loss of life.

The Gulf of Mexico was likely formed roughly 300 million years ago when part of the ocean floor gradually sank due to plate tectonics. Here are five key facts about the oil … There is extreme variability in both current direction and speed on the continental shelf and in the coastal waters of the gulf, where currents are subjected to seasonal and annual variations caused not only by major circulation patterns but also by changes in the prevailing wind direction. On the shelf and on the slope that dips downward to the abyssal plain, buried salt domes occur at various depths; economically important deposits of oil and natural gas are associated with them. The Straits of Florida divides the Gulf from the Atlantic Ocean, while the Yucatan Channel separates it from the Caribbean Sea. Siempre 50, no. miles (1.5 million sq km), and is measured 994 miles (1,600 km) west to east, and 559 miles (900 km) north to south.Though somewhat shallow along the coastal continental shelf areas, it plunges to an (estimated) maximum depth of over 13,123 ft.

Expansion along the gulf ended there, as antebellum efforts to purchase Cuba for its sugar plantations and strategic position failed. Carbon dioxide is transferred to the atmosphere in regions of upwelling.

From the floor of the basin rise the Sigsbee Knolls, some of which attain heights of 1,300 feet (400 metres); these are surface expressions of the buried salt domes. Many onshore refineries and offshore drilling platforms operate in the Gulf area, and produce about a quarter of the crude oil and almost one third of the natural gas in the United States. SEDIMENT: Solid unconsolidated rock and mineral fragments that come from the weathering of rocks and are transported by water, air, or ice and form layers on Earth's surface.
