Quick Answer: Which Mid Ocean Ridge Is Spreading The Slowest?

Is the East Pacific Rise spreading faster or slower than the Mid Atlantic Ridge?

The Mid-Atlantic Ridge, for instance, is a slow spreading center.

It spreads 2-5 centimeters (.

8-2 inches) every year and forms an ocean trench about the size of the Grand Canyon.

The East Pacific Rise, on the other hand, is a fast spreading center..

What is an example of mid ocean ridge?

Mid-ocean ridges form where two tectonic plates are pulling apart, also called seafloor spreading. … The Mid-Atlantic Ridge, which is spreading one to two inches a year, along with the East Pacific Rise, which is spreading two to six inches a year, are two examples of very long mid-ocean ridges.

What is a spreading ridge?

An oceanic spreading ridge is the fracture zone along the ocean bottom where molten mantle material comes to the surface, thus creating new crust. This fracture can be seen beneath the ocean as a line of ridges that form as molten rock reaches the ocean bottom and solidifies.

What is a mid ocean ridge simple definition?

: an elevated region with a central valley on an ocean floor at the boundary between two diverging tectonic plates where new crust forms from upwelling magma.

What would happen if the Mid Atlantic Ridge stopped creating new land?

Answer Expert Verified Once it moves apart, lava will fill the new space and will then be cooled by the ocean, forming new rock. If the mid-atlantic ridge stops forming new rocks, then we wouldn’t have new land / soil to plant food into and get resources from.

What is another name for a mid ocean ridge?

A mid-ocean ridge (MOR) is a seafloor mountain system formed by plate tectonics. … Most oceanic spreading centers are not in the middle of their hosting ocean basis but regardless, are traditionally called mid-ocean ridges.

What does the ocean floor look like at Mid Ocean Ridge?

In the Atlantic Ocean, the mid-ocean ridge is called the Mid-Atlantic Ridge. … Pacific Rise have smoother topography at the ridge crest, and look somewhat like domes. They have relief of 100 to 200 meters (328 to 656 feet). The East Pacific Rise moves at an average of 15 centimeters (5.9 inches) per year.

Which mid ocean ridge is spreading the fastest?

Some of our recent research involves hydrothermal and structural investigations along Earth’s fastest seafloor spreading center, the 28°S–32°S East Pacific Rise. The fastest present-day seafloor spreading, ~150 km/Myr, occurs along the Pacific-Nazca boundary between the Easter and Juan Fernandez microplates.

What parts of the ridge have slower spreading rates?

The speed of spreading affects the shape of a ridge – slower spreading rates result in steep, irregular topography while faster spreading rates produce much wider profiles and more gentle slopes. Two well-studied mid-ocean ridges within the global system are the Mid-Atlantic Ridge and the East Pacific Rise.

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.

What erupts through the valley of the mid ocean ridge?

What erupts through the valley of the mid ocean ridge? … At mid ocean ridge, molten material rises from the mantle and erupts. The molten material then spreads you out, pushing older rock to both sides of the ridge.

What are the two main differences in shape of fast versus slow mid ocean ridges?

Fast-spreading mid-ocean ridges have an axial high (the “rise crest”) whereas slow-spreading ridges have deep axial rift valleys. This difference in morphology is reflected in the ruggedness of the flanks of ridges.
