    The Atlantic Ocean is the second-largest of the world's oceans, with an area of about 106,460,000 km 2 (41,100,000 sq mi). It covers approximately 20 percent of Earth's surface and about 29 percent of its water surface area. It is known to separate the "Old World" from the "New World" in the European perception of the World.

    The Atlantic formed when the Americas moved west from Eurasia and Africa. This began sometime in the Cretaceous period, roughly 135 million years ago. It was part of the break-up of the supercontinent Pangaea. The east coast of South America is shaped somewhat like the west coast of Africa, and this gave a clue that continents moved over long periods of time (continental drift). The Atlantic Ocean is still growing now, because of sea-floor spreading from the mid-Atlantic Ridge, while the Pacific Ocean is said to be shrinking because the sea floor is folding under itselfor subducting into the mantle.

    The Atlantic Ocean is bounded on the west by North and South America. It connects to the Arctic Ocean through the Denmark Strait, Greenland Sea, Norwegian Sea and Barents Sea. It connects with the Mediterranean Sea through the Strait of Gibraltar. In the southeast, the Atlantic merges into the Indian Ocean. The 20° East meridiandefines its border. In the southwest, the Drake Passage connects it to the Pacific Ocean. The Panama Canallinks the Atlantic and Pacific. The Atlantic Ocean is second in size to the Pacific. It occupies an area of about 106,400,000 square kilometres (41,100,000 sq mi). The volume of the Atlantic, along with its adjacent seas (the seas next to it), is 354,700,000 cubic kilometres. The average depth of the Atlantic, along with its adjacent seas, is 3,339 metres (1,826 fathoms; 10,955 ft). The greatest depth is Milwaukee Deep near Puerto Rico, where the Ocean is 8,380 metres (4,580 fathoms; 27,490 ft) deep.

    The main feature of the Atlantic Ocean's seabed is a large underwater mountain chain called the Mid-Atlantic Ridge. It runs from north to south under the Ocean. This is at the boundary of four tectonic plates: Eurasian, North American, South American and African.The ridge extends from Iceland in the north to about 58° south. The salinity of the surface waters of the open ocean ranges from 33–37 parts per thousand and varies with latitudeand season.

    From Wikipedia, the free encyclopedia This is a list of islands in the Atlantic Ocean, the largest of which is Greenland. Note that the IHO definition of the ocean excludes the seas, gulfs, bays, etc., bordering the ocean itself. Thus, for instance, not all of the islands of the United Kingdom are actually in or bordering on the Atlantic.

    The phrases "the ocean" or "the sea" used without specification refer to the interconnected body of salt water covering the majority of the Earth's surface. it includes the Atlantic, Pacific, Indian, Southern and Arctic Oceans. As a general term, "the ocean" is mostly interchangeable with "the sea" in American English, but not in British English. Strictly speaking, a sea is a body of water (generally a division of the world ocean) partly or fully enclosed by land. The word "sea" can also be used for many specific, much smaller bodies of seawater, such as the North Sea or the Red Sea. There is no sharp distinction between seas and oceans, though generally seas are smaller, and are often partly (as marginal seas) or wholly (as inland seas) bordered by land. The global, interconnected body of salt water is sometimes referred to as the "World Ocean" or global ocean. The concept of a continuous body of water with relatively free interchange among its parts is of fundamental importance to...

    Oceanic divisions

    The major oceanic divisions – listed below in descending order of area and volume – are defined in part by the continents, various archipelagos, and other criteria. Oceans are fringed by smaller, adjoining bodies of water such as, seas, gulfs, bays, bights, and straits.

    Ocean ridges

    The mid-ocean ridges of the world are connected and form a single global mid-oceanic ridge system that is part of every ocean and the longest mountain range in the world. The continuous mountain range is 65,000 km (40,000 mi) long (several times longer than the Andes, the longest continental mountain range).

    Physical properties

    The total mass of the hydrosphere is about 1.4 quintillion tonnes (1.4×1018 long tons or 1.5×1018 short tons), which is about 0.023% of Earth's total mass. Less than 3% is freshwater; the rest is saltwater, almost all of which is in the ocean. The area of the World Ocean is about 361.9 million square kilometers (139.7 million square miles), which covers about 70.9% of Earth's surface, and its volume is approximately 1.335 billion cubic kilometers (320.3 million cubic miles). This can be thoug...

    Biology

    Oceans have a significant effect on the biosphere. Oceanic evaporation, as a phase of the water cycle, is the source of most rainfall, and ocean temperatures determine climate and wind patterns that affect life on land. Life within the ocean evolved 3 billion years prior to life on land. Both the depth and the distance from shore strongly influence the biodiversityof the plants and animals present in each region. As it is thought that life evolved in the ocean, the diversity of life is immens...

    Salinity

    A zone of rapid salinity increase with depth is called a halocline. The temperature of maximum density of seawater decreases as its salt content increases. Freezing temperature of water decreases with salinity, and boiling temperature of water increases with salinity. Typical seawater freezes at around −2 °C at atmospheric pressure.If precipitation exceeds evaporation, as is the case in polar and temperate regions, salinity will be lower. If evaporation exceeds precipitation, as is the case i...

    Economic value

    Many of the world's goods are moved by ship between the world's seaports. Oceans are also the major supply source for the fishing industry. Some of the major harvests are shrimp, fish, crabs, and lobster.

    Humans have been using the ocean for a variety of purposes, for example navigation, exploration, war, travel, trade, food, leisure, power generation, extractive industries.

    Human activities affect marine life and marine habitats through overfishing, habitat loss, the introduction of invasive species, ocean pollution, ocean acidification and ocean warming. These impact marine ecosystems and food webs and may result in consequences as yet unrecognized for the biodiversityand continuation of marine life forms.

    Although Earth is the only known planet with large stable bodies of liquid water on its surface and the only one in the Solar System, other celestial bodies are thought to have large oceans. In June 2020, NASA scientists reported that it's likely that exoplanets with oceans may be common in the Milky Way galaxy, based on mathematical modeling studies.

    In March 2004, Catarina was the first hurricane-intensity tropical cyclone to be recorded in the Southern Atlantic Ocean. Since 2011, the Brazilian Navy Hydrographic Center has started to use the same scale as the North Atlantic Ocean for tropical cyclones in the South Atlantic Ocean and assign names to those which reach 35 kn (65 km/h; 40 mph).
