What is the difference between a mid ocean ridge and a rift valley think about the different plates involved and what happens?

Divergent Plate Boundaries Plates move apart at mid-ocean ridges where new seafloor forms. Between the two plates is a rift valley. Lava flows at the surface cool rapidly to become basalt, but deeper in the crust, magma cools more slowly to form gabbro.

What type of plate boundary forms a mid ocean ridge or rift valley?

divergent plate boundaries
Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt.

What type of plate is the Mid Ocean Ridge?

divergent plate boundary
Description: The Mid-Atlantic Ridge (MAR) is known as a mid-ocean ridge, an underwater mountain system formed by plate tectonics. It is the result of a divergent plate boundary that runs from 87° N – about 333 km (207 mi) south of the North Pole – to 54 °S, just north of the coast of Antarctica.

What type of boundary is a rift valley?

Many rift valleys are part of “triple junctions,” a type of divergent boundary where three tectonic plates meet at about 120° angles. Two arms of the triple junction can split to form an entire ocean. The third, “failed rift” or aulacogen, may become a rift valley.

What is the difference between rift valley and a mid ocean ridge?

The major difference between different types is what type of plate the divergent boundary is between. If the boundary is found between two continental plates you are left with a rift valley. If two oceanic plates begin moving away from each other it creates a mid-oceanic ridge.

What is the comparison between rift valley and Mid Ocean Ridge?

A rift valley is different from a mid ocean with respect to the tectonic plates. Apart from a widening valley, it equally contributes to steep mountain sides spreading. A mid-oceanic ridge is naturally produced if two oceanic plates naturally start moving away from each other.

What is the difference between rift valley and Mid Ocean Ridge?

Which is a rift valley?

A rift valley is a lowland region formed by the interaction of Earth’s tectonic plates. A rift valley is a lowland region that forms where Earth’s tectonic plates move apart, or rift. Rift valleys are found both on land and at the bottom of the ocean, where they are created by the process of seafloor spreading.

What is the difference between mid-ocean ridges and rift valleys?

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 the difference between a rift valley and Mid-ocean Ridge?

Is a rift valley convergent or divergent?

Areas where plates are colliding form convergent boundaries, and areas where plates are expanding create divergent boundaries. Rift valleys are formed by divergent boundaries that involve continental plates.

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 big is the Rift Valley in the Pacific Ocean?

Over millions of years, the Mid-Atlantic Ridge has formed rift valleys as wide as 15 kilometers (9 miles). In the Pacific Ocean, the East Pacific Rise has created rift valleys where the Pacific plate is separating from the North American plate, Cocos plate, Nazca plate, and Antarctic plate.

What causes the mid ocean ridge to form?

Mid-ocean ridges occur along divergent plate boundaries, where new ocean floor is created as the Earth’s tectonic plates spread apart. As the plates separate, molten rock rises to the seafloor, producing enormous volcanic eruptions of basalt. The speed of spreading affects the shape of a ridge – slower spreading rates result in steep,

What happens at the bottom of the Rift Valley?

As tectonic plates move away from one another at mid-ocean ridges, molten rock from the mantle may well up and harden as it contacts the frigid sea, forming new oceanic crust at the bottom of the rift valley.
