Sea-floor spreading due to convection currents in the Earth's mantle (although this is still under investigation). Magma is pushed up through the cracks in the sea-floor as the plates move apart.

Melted material that rises from the mantle is called?

Melted material that rises from the mantle is called magma. Once magma reaches the Earth's surface, it is then referred to as lava.


In which location would an ocean ridge most likely to be located?

An ocean ridge is most likely to be located at the boundary where two tectonic plates are moving apart, such as the Mid-Atlantic Ridge. This is where new oceanic crust is formed as magma rises to the surface and solidifies, creating a ridge-like structure along the seafloor.


How was the Mid-Atlantic Ridge formed?

The Mid-Atlantic Ridge was formed by the divergent boundary between the North American Plate and Eurasian Plate (to the east) and the South American Plate and African Plate (to the west). As these plates move away from each other, magma rises to the surface, solidifies, and forms new oceanic crust, creating the ridge.


Is new oceanic crust formed at a mid-ocean ridge?

Yes, new oceanic crust is formed at mid-ocean ridges through a process called seafloor spreading. Magma rises from the mantle through the ridge, cools and solidifies to form new crust. This process helps in constantly renewing the oceanic crust.


What happens when new basalt forms along mid ocean ridges it?

The molten material then spreads out, pushing the older rock to both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. Then more molten material flows into the crack. The material splits apart the strip of solid rock that formed before, pushing it aside.

Does magma produce new material when it rises from an ocean ridge?

Yes, when magma rises from an ocean ridge, it can produce new material through a process called seafloor spreading. As the magma reaches the surface, it cools and solidifies, forming new oceanic crust. This process contributes to the continuous expansion of the seafloor and the formation of new crustal material.

In sea-floor spreading molten material rises from the mantle and erupts .?

When spreading molten material rises from the mantle in the sea-floor and erupts, it can create sea mounts, which are underwater mountains. If enough material is ejected, the mounts will break through the surface of the water to create islands.


What are the steps in the process of sea-flooring?

The sea-floor spreading begins at the mid-ocean ridge, which forms along a crack in the oceanic crust. Along the ridge, molten material that forms several kilometers beneath the surface, rises and erupts. At the same time, older rock moves outward on both sides of the ridge. As the molten material cools, it forms a strip of solid rock in the center of the ridge. When more molten material flows into the crack, it forms a new strip of rock.

An underwater ridge rising close to the surface is called a reef. A reef is typically made of rock, sand or coral that lies 80 meters or less beneath low water.
