Atlantic Ocean

In hydrology, an oceanic basin (or ocean basin) is anywhere on Earth that is covered by seawater. Geologically, most of the ocean basins are large geologic basins that are below sea level.

Most commonly the ocean is divided into basins following the continents distribution: the North and South Atlantic (together approximately 75 million km/ 29 million mi), North and South Pacific (together approximately 155 million km/ 59 million mi), Indian Ocean (68 million km/ 26 million mi) and Arctic Ocean (14 million km/ 5.4 million mi). Also recognized is the Southern Ocean (20 million km/ 7 million mi). All ocean basins collectively cover 67% of the Earth's surface, and together they contain almost 97% of all water on the planet. They have an average depth of almost 4 km (about 2.5 miles).

Florida (/ˈflɒrɪdə/ FLORR-ih-də; Spanish: [floˈɾiða] ) is a state in the Southeastern and South Atlanticregions of the United States. It borders the Gulf of Mexico to the west, Alabama to the northwest, Georgia to the north, the Atlantic Ocean to the east, the Straits of Florida to the south, and The Bahamas to the southeast. About two-thirds of Florida occupies a peninsula between the Gulf of Mexico and the Atlantic Ocean. It has the longest coastline in the contiguous United States, spanning approximately 1,350 miles (2,170 km), not including its many barrier islands. It is the only state that borders both the Gulf of Mexico and the Atlantic Ocean. With a population of over 23 million, it is the third-most populous state in the United States and ranks seventh in population density as of 2020. Florida spans 65,758 square miles (170,310 km), ranking 22nd in area among the states. The Miami metropolitan area, anchored by the cities of Miami, Fort Lauderdale, and West Palm Beach, is the state's largest metropolitan area, with a population of 6.138 million; the most populous city is Jacksonville. Florida's other major population centers include Tampa Bay, Orlando, Cape Coral, and the state capital of Tallahassee.

Various Native American groups have inhabited Florida for at least 14,000 years. In 1513, Spanish explorer Juan Ponce de León became the first documented European to make landfall in the region and named it La Florida (Spanish for "land of flowers"; [la floˈɾiða]), giving the territory its present name. Spain subsequently incorporated Florida into the Spanish Empire in the early 16th century. In 1565, it founded St. Augustine, the oldest continuously inhabited European-established settlement in the continental United States. The region was frequently coveted and attacked by Great Britain throughout the 18th century. Britain briefly gained control of Florida in 1763, but Spain recovered it in 1783 following the British defeat in the American Revolutionary War. Florida remained under Spanish rule until it was ceded to the United States in 1821, in exchange for U.S. recognition of Spanish sovereignty in Texas and the resolution of the border dispute along the Sabine River. Florida was admitted as the 27th state on March 3, 1845, and was the principal location of the Seminole Wars (1816–1858), the longest and most extensive of the American Indian Wars. The state seceded from the Union on January 10, 1861, becoming one of the seven original Confederate States, and was readmitted to the Union after the Civil War on June 25, 1868.

Cádiz (/kəˈdɪz/ kə-DIZ, US also /ˈkeɪdɪz, ˈkæd-, ˈkɑːd-/ KAY-diz, KA(H)D-iz, Spanish: [ˈkaðiθ]) is a city in Spain and the capital of the Province of Cádiz in the autonomous community of Andalusia. It is located in the southwest of the Iberian Peninsula off the Atlantic Ocean separated from neighbouring San Fernando by a narrow isthmus. One of the oldest continuously inhabited cities in Western Europe, Cádiz was founded by the Phoenicians as a trading post. In the 18th century, the Port in the Bay of Cádiz consolidated as the main harbour of mainland Spain, enjoying the virtual monopoly of trade with the Americas until 1778. It is also the site of the University of Cádiz.

Situated on a narrow slice of land surrounded by the sea‚ Cádiz is, in most respects, a typical Andalusian city with well-preserved historical landmarks. The older part of Cádiz, within the remnants of the city walls, is commonly referred to as the Old Town (Spanish: Casco Antiguo), and represents a large area of the total size of the city. It is characterized by the antiquity of its various quarters (barrios), among them El Pópulo, La Viña, and Santa María, which present a marked contrast to the newer areas of town. While the Old City's street plan consists of narrow winding alleys connecting large plazas, newer areas of Cádiz typically have wide avenues and more modern buildings. The city is dotted with parks where exotic plants flourish, including giant trees supposedly brought to the Iberian Peninsula from the New World. This includes the historic Parque Genovés.

The Gulf of St. Lawrence is a gulf that fringes the shores of the provinces of Quebec, New Brunswick, Nova Scotia, Prince Edward Island, Newfoundland and Labrador, in Canada, plus the islands Saint-Pierre and Miquelon, possessions of France, in North America.

The Gulf of St. Lawrence connects the Great Lakes to the Atlantic Ocean via the St. Lawrence River.

Lake Superior is a lake in central North America. The northernmost, westernmost, and highest of the Great Lakes, Lake Superior straddles the Canada–United States border with the Canadian province of Ontario to the north and east and the U.S. states of Minnesota to the west and Michigan and Wisconsin to the south. It is the largest freshwater lake in the world by surface area and the third-largest freshwater lake by volume. It drains into Lake Huron via St. Marys River, then through the lower Great Lakes to the St. Lawrence River and ultimately the Atlantic Ocean.

The St. Lawrence River (French: Fleuve Saint-Laurent, pronounced [flœv sɛ̃ lɔʁɑ̃]) is a large international river in the middle latitudes of North America connecting the Great Lakes to the North Atlantic Ocean. Its waters flow in a northeasterly direction from Lake Ontario to the Gulf of St. Lawrence, traversing Ontario and Quebec in Canada and New York in the United States. A section of the river demarcates the Canada–U.S. border.

As the primary drainage outflow of the Great Lakes Basin, the St. Lawrence has the second-highest discharge of any river in North America (after the Mississippi River) and the 16th-highest in the world. The estuary of the St. Lawrence is often cited by scientists as the largest in the world. Significant natural landmarks of the river and estuary include the 1,864 river islands of the Thousand Islands, the endangered whales of Saguenay–St. Lawrence Marine Park, and the limestone monoliths of the Mingan Archipelago.

The Río de la Plata (Spanish pronunciation: [ˈri.o ðe la ˈplata] ; lit. 'River of Silver'), also called the River Plate or La Plata River in English, is the estuary formed by the confluence of the Uruguay River and the Paraná River at Punta Gorda. It empties into the Atlantic Ocean and forms a funnel-shaped indentation on the southeastern coastline of South America. Depending on the geographer, the Río de la Plata may be considered a river, an estuary, a gulf, or a marginal sea. If considered a river, it is the widest in the world, with a maximum width of 220 kilometres (140 mi).

The river is about 290 kilometres (180 mi) long and widens from about 2 kilometres (1.2 mi) at its source to about 220 kilometres (140 mi) at its mouth. It forms part of the border between Argentina and Uruguay. The name Río de la Plata is also used to refer to the populations along the estuary, especially the main port cities of Buenos Aires and Montevideo, where Rioplatense Spanish is spoken and tango culture developed. The coasts of the river are the most densely populated areas of Uruguay and Argentina.

Uruguay, officially the Oriental Republic of Uruguay, is a country in South America. It shares borders with Argentina to its west and southwest and Brazil to its north and northeast, while bordering the Río de la Plata to the south and the Atlantic Ocean to the southeast. It is part of the Southern Cone region of South America. Uruguay covers an area of approximately 176,215 square kilometers (68,037 sq mi). It has a population of almost 3.5 million people, of whom nearly 2 million live in the metropolitan area of its capital and largest city, Montevideo.

The area that became Uruguay was first inhabited by groups of hunter gatherers 13,000 years ago. The first European explorer to reach the region was Juan Díaz de Solís in 1516, but the area was colonized later than its neighbors. At the time of European arrival, the Charrúa were the predominant tribe, alongside other groups such as the Guaraní and the Chaná. However, none of these groups were socially or politically organized, which contributed to their decline. Amid territorial disputes, the Portuguese established Colônia do Sacramento in 1680, and the Spanish founded Montevideo as a military stronghold. Uruguay secured its independence between 1811 and 1828, following a four-way struggle involving Portugal, Spain, and later the United Provinces of the Río de la Plata and the Empire of Brazil. In 1830, the country enacted its constitution and was formally established as an independent state.

The ocean is the body of salt water that covers approximately 70.8% of Earth. The ocean is conventionally divided into large bodies of water, which are also referred to as oceans (in descending order: the Pacific Ocean, the Atlantic Ocean, the Indian Ocean, the Antarctic/Southern Ocean, and the Arctic Ocean), and are themselves mostly divided into seas, gulfs and subsequent bodies of water. The ocean contains 97% of Earth's water and is the primary component of Earth's hydrosphere, acting as a huge reservoir of heat for Earth's energy budget, as well as for its carbon cycle and water cycle, forming the basis for climate and weather patterns worldwide. The ocean is essential to life on Earth, harbouring most of Earth's animals and protist life, originating photosynthesis and therefore Earth's atmospheric oxygen, still supplying half of it.

Ocean scientists split the ocean into vertical and horizontal zones based on physical and biological conditions. Horizontally the ocean covers the oceanic crust, which it shapes. Where the ocean meets dry land it covers relatively shallow continental shelfs, which are part of Earth's continental crust. Human activity is mostly coastal with high negative impacts on marine life. Vertically the pelagic zone is the open ocean's water column from the surface to the ocean floor. The water column is further divided into zones based on depth and the amount of light present. The photic zone starts at the surface and is defined to be "the depth at which light intensity is only 1% of the surface value" (approximately 200 m in the open ocean). This is the zone where photosynthesis can occur. In this process plants and microscopic algae (free-floating phytoplankton) use light, water, carbon dioxide, and nutrients to produce organic matter. As a result, the photic zone is the most biodiverse and the source of the food supply which sustains most of the ocean ecosystem. Light can only penetrate a few hundred more meters; the rest of the deeper ocean is cold and dark (these zones are called mesopelagic and aphotic zones).

Massachusetts (/ˌmæsəˈtʃuːsɪts/ /-zɪts/ MASS-ə-CHOO-sits, -⁠zits; Massachusett: Muhsachuweesut [məhswatʃəwiːsət]), officially the Commonwealth of Massachusetts, is a state in the New England region of the Northeastern United States. It borders the Atlantic Ocean and the Gulf of Maine to its east, Connecticut and Rhode Island to its south, New Hampshire and Vermont to its north, and New York to its west. Massachusetts is the seventh-smallest state by land area. With an estimated population of over 7.1 million, it is the most populous state in New England, the 16th-most-populous in the United States, and the third-most densely populated U.S. state, after New Jersey and Rhode Island.

Massachusetts was a site of early English colonization. The Plymouth Colony was founded in 1620 by the Pilgrims of Mayflower. In 1630, the Massachusetts Bay Colony, taking its name from the Indigenous Massachusett people, also established settlements in Boston and Salem. In 1692, the town of Salem and surrounding areas experienced one of America's most infamous cases of mass hysteria, the Salem witch trials. The American Revolution originated in Massachusetts, with Boston becoming known as the "Cradle of Liberty" for its political agitation. In 1786, Shays' Rebellion, a populist revolt, influenced the United States Constitutional Convention. Originally dependent on agriculture, fishing, and trade, Massachusetts transformed into a manufacturing hub during the Industrial Revolution. Before the American Civil War, the state was a center for the abolitionist, temperance, and transcendentalist movements. During the 20th century, the state's economy shifted from manufacturing to services; in the 21st century, Massachusetts has become the global leader in biotechnology, and also excels in artificial intelligence, engineering, higher education, finance, and maritime trade.
