Place Where Two Oceans Meets But Doesn't Mix | Desert illusion
The borders of the oceans are the limits of the Earth's oceanic waters. The definition and number of oceans can vary depending on the adopted . The Atlantic Ocean separates the Americas from Europe and Africa. .. Cape Leeuwin in Western Australia is described as the point where the Indian and Southern Oceans meet. Originally Answered: Why does the water from the Atlantic and Indian Ocean not the Gulf of Mexico, and the Caribbean Sea on the west and the Baltic, North, in the water where the Atlantic Ocean meets the Indian Ocean and if so, why?. The oceans meet at a point on the island. Cetain quad tours will take you to this point. Bavaro is in the carrabean part. It is beautiful and well.
There are also some locations that are arid climates with considerable drought in some years. Rainfall varies with elevation, size and water currents cool upwelling keep the ABC islands arid. Warm, moist trade winds blow consistently from the east, creating both rain forest and semi arid climates across the region. While landfalls are infrequent, the resulting loss of life and property damage makes them significant hazard to life in the Caribbean. Tropical cyclones that impact the Caribbean often develop off the West coast of Africa and make their way west across the Atlantic Ocean toward the Caribbean, while other storms develop in the Caribbean itself.
The Caribbean hurricane season as a whole lasts from June through November, with the majority of hurricanes occurring during August and September. On average around 9 tropical storms form each year, with 5 reaching hurricane strength. According to the National Hurricane Center hurricanes occurred in the Caribbean between and Flora and fauna[ edit ] Vegetation[ edit ] The vegetation of the region is mostly tropical but differences in topographysoil and climatic conditions increase species diversity.
Where there are porous limestone terraced islands these are generally poor in nutrients. It is estimated that 13, species of plants grow in the Caribbean of which 6, are endemic. For example, guaiac wood Guaiacum officinalethe flower of which is the national flower of Jamaica and the Bayahibe rose Pereskia quisqueyana which is the national flower of the Dominican Republic and the ceiba which is the national tree of both Puerto Rico and Guatemala.
The mahogany is the national tree of the Dominican Republic and Belize. The caimito Chrysophyllum cainito grows throughout the Caribbean. In coastal zones there are coconut palms and in lagoons and estuaries are found thick areas of black mangrove and red mangrove Rhizophora mangle. In shallow water flora and fauna is concentrated around coral reefs where there is little variation in water temperature, purity and salinity.
Leeward side of lagoons provide areas of growth for sea grasses. In brackish water of harbours and estuaries at depths less than 2. The Central American Sea apparently became separated from the Atlantic before the end of the first phase. Near the end of the second phase, gentle warping and faulting occurred, forming the Aves and Beata ridges.
Forces producing the Panamanian isthmus and the Antillean arc were vertical, resulting in no ultimate horizontal movement.

The sediment beds tend to arch in the middle of the basins and to dip as landmasses are approached. The younger Cenozoic beds formed during the last 65 million years are generally horizontal, having been laid down after the deformations occurred.
Connections were established with the Pacific Ocean during the Cretaceous Period from about to 66 million years ago but were broken when the land bridges that permitted mammals to cross between North and South America were formed in the Miocene and Pliocene epochs about 23 to 2.
The existing sediment cover of the seabed consists of red clay in the deep basins and trenches, globigerina ooze a calcareous marine deposit on the rises, and pteropod ooze on the ridges and continental slopes.
Clay minerals appear to have been washed down by the Amazon and Orinoco rivers, as well as by the Magdalena River in Colombia. Coral reefs fringe most of the islands. Physiography The Caribbean Sea is divided into five submarine basins, each roughly elliptical in shape, which are separated from one another by submerged ridges and rises.
The Nicaraguan Rise, a wide triangular ridge with a sill depth of about 4, feet 1, metresextends from Honduras and Nicaragua to Hispaniola, bearing the island of Jamaica and separating the Cayman Basin from the Colombian Basin. The basins are connected by the submerged Aruba Gap at depths greater than 13, feet 4, metres.
The Aves Ridge, incomplete at its southern extremity, separates the Venezuelan Basin from the small Grenada Basin, which is bounded to the east by the Antillean arc of islands. Subsurface water enters the Caribbean Sea across two sills.
These sills are located below the Anegada Passagewhich runs between the Virgin Islands and the Lesser Antilles, and the Windward Passagewhich stretches between Cuba and Hispaniola. The sill depth of Anegada Passage is between 6, and 7, feet 1, and 2, metreswhereas that of the Windward Passage is between 5, and 5, feet 1, and 1, metres. Hydrology North Atlantic deep water enters the Caribbean beneath the Windward Passage and is characterized by its rich oxygen content and by a salinity of slightly less than 35 parts per thousand.
This Caribbean bottom water also enters the Venezuelan Basin, thus introducing high-oxygen water at depths of 5, to 9, feet 1, to 3, metres.
Subantarctic intermediate water i. Above this water, the subtropical undercurrent and surface water enter.
Surface currentsbearing both high- and low-salinity water depending on the source, enter the Caribbean mainly through the channels and passages of the southern Antilles. The remainder is the surface water that passed over the Antillean arc at depths of less than 2, feet metres.

Climate The climate of the Caribbean generally is tropicalbut there are great local variations, depending on mountain elevation, water currents, and the trade winds. Rainfall varies from about 10 inches 25 cm per year on the island of Bonaire off the coast of Venezuela to some inches cm annually in parts of Dominica.
The northeast trade winds dominate the region with an average velocity of 10 to 20 miles 16 to 32 km per hour. Tropical storms reaching a hurricane velocity of more than 75 miles km per hour are seasonally common in the northern Caribbean as well as in the Gulf of Mexico; they are almost nonexistent in the far south. The hurricane season is from June to November, but hurricanes occur most frequently in September.
The yearly average is about eight such storms. The Caribbean has fewer hurricanes than either the western Pacific where these storms are called typhoons or the Gulf of Mexico. Most hurricanes form in the eastern Atlantic near the Cape Verde Islands and follow the path of the trade winds into the Caribbean and the Gulf of Mexico, although the exact path of any hurricane is unpredictable.
In one of the deadliest hurricanes on record, Flora, caused the loss of more than 7, lives and extensive property damage in the Caribbean alone. Such storms also have been a major cause of crop failure in the region. Infrared satellite image of Hurricane Charley right approaching Cuba, Aug.
AP Economic aspects Resources While the vegetation of the Caribbean region is generally tropical, variations in topographysoils, rainfall, humidity, and soil nutrients have made it diverse. The porous limestone terraces of the islands are generally nutrient-poor. Near the seashore, black and red mangroves form dense forests around lagoons and estuaries, and coconut palms typify the sandy vegetation of the littoral.
Both the Central American region and the Antillean islands are on the routes of birds migrating to or from North Americaso that large seasonal variations occur in the bird populations. Parrotsbananaquitsand toucans are typical resident Caribbean birds, while frigate birdsboobiesand tropic birds can be seen over the open ocean.

The marine biota is derived from the Indian and western Pacific oceans via the Panamanic Seaway, which was closed by the rise of the Isthmus of Panama some four million years ago.
