What are the Seven Seas?
Where to Spot the Atlantic and the Pacific—At The Same Time The Western Hemisphere's most landlocked point is near the tiny Indian reservation town of Allen, South Dakota, You'll see the sun rising out the Caribbean to your east, if the coast You can head back toward the ocean of your choice. This is where two oceans meet – the cold waters of the Atlantic Ocean on the west and the warmer Indian Ocean waters on the east. But is Cape Point's claim to. Cape Point, where the Indian Ocean meets the Atlantic, at the tip of the Cape Peninsula, South Bonaire, Netherlands Antilles, Caribbean, Atlantic Ocean.
Geology Origin and development The origin and development of the Atlantic Ocean are now accounted for by the theories of continental drift and plate tectonicsaccording to which a vast protocontinent, Pangeabegan to break up about million years ago. The rifting caused the landmasses of the Western and Eastern hemispheres to separate, opening up the Atlantic Ocean basin.
As can be seen on a map of the world, the continental coastlines of North America and Europe and of South America and Africa almost match. If the edges of the continental shelves are matched, the fit is nearly perfect.
Other geologic and paleontological similarities found on both sides of the Atlantic substantiate the theory of plate tectonics and thus help explain the evolution of the Atlantic.
Perhaps the most conclusive evidence bearing out this theory of origin is to be found in the existence of the Mid-Atlantic Ridge. The ridge is in effect a long rift zone of mountains, volcanoes, and faulted plateaus.
A high heat flowwhich is associated with the extrusion of magma and with seafloor spreadingexists in the rift zone.
The newer rock is composed mainly of gabbro a coarse-grained rock formed deep within the mantle under heat and pressurebasalt a rock that originally poured out at the surface in molten formand serpentine a common rock-forming mineral.
Consequent movement of the ocean floor and of the continents in opposite directions outward from the ridge is widening the Atlantic basin at an estimated rate of about 0. The worldwide average rate has been estimated at 1 inch 2. Corresponding spreading is occurring at an even faster pace in the Pacific Ocean ; in the Atlantic, however, the slower rate of spreading causes the flanks of the ridge to be built up steeply by accumulating lava.
The physiography and geology of the Mid-Atlantic Ridge have been the subject of much scientific study, as has the geology of the Atlantic as a whole.
Research has focused on refinement of the theory of plate tectonics. In addition, competing subtheories have been developed regarding the large-scale dynamics and cyclicity of tectonic processes, the effects of heat loss and conduction through oceanic and continental crusts, and relative rates of crustal spreading. LaMourie Bottom deposits The greater part of the bottom of the Atlantic is covered with calcareous ooze.
At depths greater than 16, feet 5, metresthe calcium carbonate content decreases, and the calcareous deposits give way to red clay. The finer material is not evident on submarine ridges, and the shells of pteropod gastropods mollusks of the gastropod class comprising the snails may be sufficiently abundant there to characterize the deposits as pteropod ooze.
It is also bounded by the Antarctic Ocean in the south and the Arctic Ocean in the north. The Pacific Ocean extends to about , square kilometers and it also has the longest shoreline that totals to approximatelykilometers.
The Pacific Ocean has very limited occurrences of damaging ocean currents or movements, which makes it a peaceful ocean. Some of the current environment concerns include: Indian Ocean The Indian Ocean is the third largest ocean in the planet.

It covers an expanse of about 73, square kilometers. Just like the Atlantic Ocean, the Indian Ocean was highly known as a voyage sea up to the 15th Century that gave it a historical marking for colonization and spice trade. For this reason, the Indian Ocean has a great record of all sorts of humankind, all the way through the world history.
Indian Ocean is encircled by eastern coast of Africa which constitutes the shores of the Middle East and India in the north. Also, the Indian Ocean has plentiful exotic animal and plant species. Beach sands are also exploited by a majority of the countries bordering the Indian Ocean particularly because they are rich in heavy metals.
The Indian Ocean is as well relatively warm compared to other oceans, which limits the growth of phytoplanktons. Gulfs, bays, and straits are also numerous within the spreads of this ocean.

Some of the environmental concerns here include: Antarctic Ocean The Antarctic Ocean is the fourth largest in the planet and only covers an area of about 20, square kilometers.
We take the ferry from El Conquistador the two kilometres to Palomino and are immediately blown away. This chunk of paradise has a mountain spine and on the south and east shores there's plenty of white-sand beach to quietly lounge and swim.
Paddle boarders, kayakers and snorkellers populate the waters close to the coast and, for those that want to make some noise and burn some gas, there's the Jet Skis.
My year-old son, Alex, and I rip around a kilometre off shore so we don't annoy those seeking solace. To repent for our lowbrow need for speed, we spend part of the afternoon communing with nature by hiking the island's jungle ascents and descents. At the top, the view is spectacular with the Atlantic to one side, the Caribbean to the other, and the larger island of Puerto Rico looming in the near distance.

We reward ourselves with a late lunch at Iguana's Cafe, so named because the reptiles are plentiful on the island and hang around for scraps.
It's a Palomino salad for me, fish and chips, made with fresh island red snapper, for my son. And to keep it Puerto Rican I have the signature Palomino Adventure cocktail of rum, coconut cream and mint, while my son has the national light beer, Medalla.
