Is oceanic lithosphere lighter than continental lithosphere?
no
What happens in sea-floor spreading?
under water volcanoes move the oceanic plates and spread them
What is the process where new oceanic lithosphere formed?
New oceanic crust is created at the mid-ocean ridges where rift volcanoes feed solidifying magma from the asthenosphere to both sides of the divergent plate boundaries. The mid-ocean ridge marks the line where heat from the Earth's interior is being carried to the surface by convection currents in the mantle. At the opposite end of the convection currents, colder, denser, and older oceanic crust is being drawn down into the asthenosphere, the birth to death of oceanic crust occurring in roughly 150 million year cycles.
The difference between plate tectonics continental drift and sea floor spreading?
Answer:Continental drift is the hypothesis that states that the continents once formed a single landmass(Pangaea) broke up and drifted to their present locations.Sea-floor spreading the process by which new oceanic lithosphere(sea floor) forms as magma rises to Earth's surface and solidifies at a mid-ocean ridge.
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.
What happens to the ocean floor the farther the the oceanic lithosphere is from a mid-ocean ridge?
Magma rises and slidifies and creates a new crust.
What happens to the ocean floor the farther the oceanic lithosphere is from a mid-ocean ridge?
Magma rises and slidifies and creates a new crust.
What happens to the ocean floor the farther the oceanic lithosphere is from the mid ocean ridge?
Magma rises and slidifies and creates a new crust.
What happens to the ocean floor farther to the oceanic lithosphere is from a mid ocean ridge?
Magma rises and slidifies and creates a new crust.
New oceanic lithosphere forms as a result of?
New oceanic lithosphere forms as a result of continental drift.
What happens at mid ocen ridges?
Creation of new ocean floor/oceanic lithosphere, at the boundary of diverging tectonic plate.
What is oceanic crust composed of?
The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.
Where on the ocean floor is sediment the thickest?
the thickest accumulation of sediment on the ocean floor is at the CONTINENTAL SLOPES AND RISES. :)
Is oceanic lithosphere lighter than continental lithosphere?
no
The oceans crust is composed of what?
The oceanic crust composed of sima, mafic rocks and basalt. This is the top layer of the lithosphere which is found in the ocean floor.
What evidence can prove that the ocean floor was moving?
Oceanic crust that was farther away from a mid-ocean ridge was older that crust closer to the ridge
What happens in sea-floor spreading?
under water volcanoes move the oceanic plates and spread them
