New crust forms?
New crust forms at spreading zones like the Mid-Atlantic ridge in the middle of the Atlantic Ocean. They occur because of ocean floor spreading.
Where does new crust come from in sea-floor spreading?
The ocean floors are crustal plates and move, carrying the continents along with them. This movement begins at a mid-ocean ridge. A ridge forms along a crack in the oceanic crust, where molten material is heated by the mantle and erupts. In this process, called sea-floor spreading, the sea floor spreads apart along both sides of a mid-ocean ridge as new crust is added. As a result, the ocean floors move like conveyor belts, carrying the continents along with them.
In sea-floor spreading what happens to the old oceanic crust as new molten material rises from the mantle?
It gets pushed out to either side of the mid-ocean ridge.
Does seafloor spreading cause the earth's crust to expand?
New oceanic crust is being created at seafloor spreading zones, and crust is alternately being subducted and destroyed at subduction zones.
When and where the trench occurs?
Trenches occur by diverging plate boundries and normally at about 11,000 meters deep. This includes sea floor spreading which is where a new layer of crust forms at the mid ocean ridge and the old crust falls into trenches
What process adds new crust to the ocean floor?
Volcanic eruptions are one process that adds new material to crust. Lava from the volcanoes eventually cool, forming new land. Sea floor spreading also adds new material to the crust.
What is this is the process of creating new oceanic crust?
Sea floor spreading

What is a good sentence for sea floor spreading?

How does new oceanic crust from at a divergent plate boundary?
Sea-Floor Spreading is your answer.

What is the process that creates new ocean crust to form molten rock?
Sea Floor Spreading
What is called when new crust forms where magma rises at mid ocean ridges?
sea floor spreading
Does sea floor spreading create or destroy new oceanic crust at mid ocean ridge?
Creates
The process of continually adds new crust to the ocean floor along both sides of the mid-ocean ridge.?
sea floor spreading
About sea floor spreading?
Sea-floor spreading is what happens when the plates in the earth's crust move apart. During this movement of the plates, magma wells up from deep within the earth and fills in the cracks, forming a new oceanic crust, or sea-floor.
