Where is the oceanic ridge located?

Where is the oceanic ridge located?

Oceanic ridges are found in every ocean basin and appear to girdle Earth. The ridges rise from depths near 5 km (3 miles) to an essentially uniform depth of about 2.6 km (1.6 miles) and are roughly symmetrical in cross section. They can be thousands of kilometres wide.

What is the mid-ocean ridge and where is it located?

Mid-Atlantic Ridge, submarine ridge lying along the north-south axis of the Atlantic Ocean; it occupies the central part of the basin between a series of flat abyssal plains that continue to the margins of the continental coasts.

What is an oceanic ridge where is there one and what is it called?

A mid-ocean ridge or mid-oceanic ridge is an underwater mountain range, formed by plate tectonics. This uplifting of the ocean floor occurs when convection currents rise in the mantle beneath the oceanic crust and create magma where two tectonic plates meet at a divergent boundary.

Which mid-ocean ridge is spreading the slowest?

The Ridge is named after him, and the name was recognized in April 1987 by SCUFN (under that body’s old name, the Sub-Committee on Geographical Names and Nomenclature of Ocean Bottom Features). The ridge is the slowest known spreading ridge on earth, with a rate of less than one centimeter per year.

Which is the deepest ocean in the world?

Pacific Mariana
The new survey has shown that the deepest point of the trench is Meteor Deep at 8265 m and is located within the waters of the Atlantic Ocean….Five deepest points of the world’s oceans.

Name Challenger Deep
Approx depth in metres 10 924
Ocean Pacific
Trench Mariana
Location 11.369°N/142.587°E

What do you expect to find in the mid-ocean ridge?

Because mid-ocean ridges are places where tectonic plates are pulling apart, you might expect to find an incredibly deep canyon, but that’s not exactly the case. As the tectonic plates pull apart, molten rock, or magma, comes up from below to fill in the gaps. Mid-ocean ridges can spread slowly or quickly.

Who discovered seafloor spreading?

Harry Hess
Harry Hess: One of the Discoverers of Seafloor Spreading.

What is the slowest spreading ocean?

The Gakkel Mid-Ocean Ridge (MOR) is the slowest spreading center on the planet with full-spreading rates between 1.33 cm/yr along the Greenland end to 0.63 cm/yr along the Siberian end.

How fast is the mid-ocean ridge expanding?

fast spreading center mid-ocean ridge where seafloor spreading is occuring at more than 100 millimeters (4 inches) a year.

Which is the roughest ocean?

The South China Sea and East Indies, eastern Mediterranean, Black Sea, North Sea, and British Isles are the most dangerous seas in the world, with the greatest number of shipping accidents in the last 15 years, according to a report released by the World Wildlife Fund (WWF).

What are the five example of ocean ridges?

This ridge system includes the Mid-Atlantic Ridge, Mid-Indian Ocean Ridge, Carlsberg Ridge, Pacific-Antarctic Ridge, and the East Pacific Rise with its related features, including the Chile Rise, Galapagos Rift Zone, Gorda Rise, and Juan de Fuca Ridge.

How big is the mid ocean ridge in miles?

Ocean Exploration Facts: NOAA Office of Ocean Exploration and Research What is the mid-ocean ridge? The mid-ocean ridge is the most extensive chain of mountains on Earth, stretching nearly 65,000 kilometers (40,390 miles) and with more than 90 percent of the mountain range lying in the deep ocean.

Is the Mid Atlantic Ridge a rift valley?

Two of the most carefully studied mid-ocean ridges are the Mid-Atlantic Ridge and the East Pacific Rise. The Mid-Atlantic Ridge runs down the center of the Atlantic Ocean, slowly spreading at a rate of two to five centimeters (0.8 to 2 inches) per year and forming a rift valley that is about the depth and width of the Grand Canyon.

How are most oceanic plateaus and seamounts formed?

Most oceanic plateaus are constructed by volcanic eruptions probably over mantle plumes Most oceanic islands and seamounts are constructed by volcanic eruptions that first occur under water Hot spots form linear island chains because the plate moves relative to the underlying hot spot

Which is likely over the oldest oceanic crust?

On the accompanying figure, which letter is likely over oceanic crust that is similar in age to that beneath letter E? B On the accompanying figure, which letter is over the oldest oceanic crust? A Island chains and seamounts cross parts of the ocean floor.
