Gulf of Mexico

The Gulf of Mexico is a big sea.

It sits near the United States and Mexico. It is also near Cuba.

The water is part of the Atlantic Ocean. It has a narrow path to reach the ocean. This makes the tides very small.

Lots of people live near the coast. Many live in the United States and Mexico.

Some people find oil under the sea. This is very important for the United States.

Water from the gulf can change the weather. It helps make storms in the land. It is a very busy place.

The Gulf of Mexico is a large sea.

It sits inside the North American continent. The United States and Mexico surround it. Cuba is also nearby.

The gulf is part of the Atlantic Ocean. It connects to the ocean through the Straits of Florida. It also connects to the Caribbean Sea. Because the paths are narrow, the tides stay very small.

Many people live along the coast. Over 15 million people live in the U.S. coastal region. About 19 million people live in the Mexican states.

Large cities like Houston and New Orleans are close to the water.

Under the sea, people find oil. This is a very important place for making fuel. The gulf provides 14% of the oil for the United States.

The gulf also affects the weather. Moisture from the water helps make storms. This can lead to bad weather in Tornado Alley. The bottom of the gulf is very deep. The deepest part is called the Sigsbee Deep. It is 12,467 feet deep.

The Gulf of Mexico is a huge body of water. It is an oceanic basin and a marginal sea of the Atlantic Ocean.

Most of the gulf is surrounded by the North American continent. The United States sits to the north and northwest. The Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo are to the south and southwest. Cuba sits near the southeast corner.

The basin has an oval shape. It connects to the Atlantic Ocean through the Straits of Florida. It also connects to the Caribbean Sea via the Yucatán Channel. Because these connections are narrow, the tidal ranges are very small.

Deep under the waves, the seafloor is made of rocks and sediments.

The basin is divided into different areas. About 32% of the gulf is the continental shelf. Another 41% is the continental slope. The rest is the abyssal plain. The deepest part of the whole basin is the Sigsbee Deep. This spot reaches a depth of 12,467 feet.

You can also find strange brine pools on the floor. These are like underwater lakes made of very salty water. This brine is much denser than the regular seawater around it. It stays in deep holes on the gulf floor.

This place has many different names in history. The Aztecs called it the 'House of Chalchiuhtlicue' after their sea deity. They even called the sea 'sky water' because it looked like the sky. The Maya people likely called it 'great water' for trade. European explorers used many names too. Hernán Cortés called it the 'Sea of the North.' Other maps called it the 'Gulf of Florida' or the 'Gulf of Cortés.' The name 'Gulf of Mexico' appeared on maps around 1550. This name became the most common one by the mid-17th century.

Life around the gulf is very busy. Many people live near the water. About 15.8 million people live in the U.S. coastal region. Major cities there include Houston, New Orleans, Mobile, and Pensacola.

In Mexico, about 19.1 million people live in the states facing the gulf. Cuba also has about 3.2 million people living near its borders. The gulf is also very important for energy. It is a top place for finding petroleum. In fact, it provides 14% of all petroleum produced in the United States.

The gulf also plays a big role in our weather. Moisture from the water moves into the air. This moisture helps create weather across the United States. It can even lead to severe weather in Tornado Alley.

The geology of the area is also very old. The gulf began to take shape about 300 million years ago. It was created when the giant supercontinent called Pangaea began to break apart. This movement of the Earth's plates stretched the crust and created the basin. Over a long time, the sea flooded the area to create the gulf we see today.

The Gulf of Mexico is a massive oceanic basin and a marginal sea of the Atlantic Ocean.

It sits mostly surrounded by the North American continent. The United States forms the northern and northwestern boundaries. To the south and southwest, the Mexican states of Tamaulipas, Veracruz, Tabasco, Campeche, Yucatán, and Quintana Roo border the water. Cuba sits near the southeast corner. The basin has a roughly oval shape. It connects to the Atlantic Ocean through the Straits of Florida. It also reaches the Caribbean Sea via the Yucatán Channel. Because these connections are quite narrow, the gulf has very small tidal ranges.

Geologically, the Gulf of Mexico is incredibly old. It began to take shape about 300 million years ago through plate tectonics. Before the late Triassic period, this area was dry land. It was part of the supercontinent known as Pangaea. At that time, a continuous mountain range stretched from Mexico through Texas and Oklahoma to Alabama. This range was linked to the Appalachian Mountains. Eventually, rifting occurred due to weaknesses in Pangaea. This process involved the collision of the Laurentia, South American, and African plates.

The formation of the basin happened in several distinct stages. First, during the late Triassic and early Jurassic, rifting created rift valleys. These valleys filled with continental red beds. Second, the continental crust stretched and thinned during the Jurassic. This created a zone of transitional crust that was only half the thickness of normal continental crust. As rifting progressed, it created connections to the Pacific and Atlantic Oceans. This flooded the opening basin to create a marginal sea. During the late Jurassic, seafloor spreading began, and oceanic crust formed. This allowed enough circulation with the Atlantic that the deposition of Louann Salt finally ceased.

The floor of the gulf is complex and varies in depth. The basin is divided into several specific regions. These include the Gulf of Mexico basin, which contains the Sigsbee Deep, and the Northeast Gulf of Mexico. Other areas include the South Florida Continental Shelf and Slope, the Campeche Bank, and the Bay of Campeche. The Western, Northwest, and the area near the Mississippi River Delta are also distinct. The seafloor consists of sedimentary rocks and recent sediments. The Sigsbee Deep is the deepest point, reaching 12,467 feet.

The basin is composed of 41% continental slope, 32% continental shelf, and 24% abyssal plain.

One of the most fascinating features of the seafloor are the brine pools. These are often called brine lakes. They occur in the northern half of the gulf. Brine is produced when gulf water touches Louann Salt along faults or sediments. This is part of a process called salt tectonics. Under pressure, the salt deforms and moves. It can rise to form salt domes or extrude along the Sigsbee Escarpment. These brine pools are extremely salty, often exceeding 200 parts-per-thousand. They are 25% or more denser than the surrounding seawater. This density prevents the brine from mixing, so it gathers in depressions on the gulf floor.

The history of the gulf's name is as varied as its geography. The Aztecs called it the 'House of Chalchiuhtlicue' after their sea deity. They referred to the sea as 'sky water.' The Maya civilization likely called it 'great water' and used it for trade. Early European explorers gave it many different names. Hernán Cortés called it the 'Sea of the North.' Other maps used names like 'Gulf of Florida' or 'Gulf of Cortés.' The name 'Gulf of Mexico' first appeared on a world map in 1550. This name is linked to the Mexica people. It became the most common name by the mid-17th century.

Today, the gulf is a vital region for people and industry. It is one of the most important offshore petroleum production regions in the world. It accounts for 14% of the total petroleum production for the United States.

Large populations live along its coasts. In 2016, 15.8 million people lived in the U.S. coastal region. Major cities include Houston, New Orleans, Mobile, and Pensacola.

In Mexico, 19.1 million people live in the coastal states. Cuba also has about 3.2 million people living near the gulf. Finally, the gulf influences global weather. Moisture from the basin contributes to weather across the United States, including severe weather in Tornado Alley.
