Old ocean floor is destroyed and absorbed by the Earth and remelted beneath what?
When the old ocean floor is destroyed, it goes to Earth's mantle.
Is the Rock found at mid ocean ridge old or young?
yes young rocks are found at mid ocean ridges not old rocks.
What made the scientists believe that the sea floor is spreading?
1. What made scientist believe that the seafloor was spreading? Samples of the deep ocean floor show that basaltic oceanic crust and overlying sediment become progressively younger as the mid-ocean ridge is approached, and the sediment cover is thinner near the ridge. Also, the rock making up the ocean floor is considerably younger than the continents, with no samples found over 200 million years old, as contrasted with maximum ages of over 3 billion years for the continental rocks. This confirms that older ocean crust has been reabsorbed in ocean trench systems. by; Vontamayosa find me on Facebook
How old are rocks in ocean crust?
The age of rocks in the ocean crust depends on where the rocks are collected. Scientists collected rock samples from the sea floor. They found out that rock samples that were closer to mid-ocean ridges were younger than the samples farther away from the ridges. So pretty much you could get rocks that are thousands of years old to over millions of year old.
Why are the Rock's close to a mid-ocean ridge younger than the ones that are farther away?
Mid-ocean ridges are basically underground volcanoes that lava from the Earth's Mantle can breach. The ocean, however, freezes the lava and that in turn forms rock. If this happens repeatedly, then the older rock gets pushed away from the source, and the younger, just formed rock is, therefore, closer to the ridge. So the younger rock being formed by the ridge is pushing away the older, previously made, igneous rock.
Explain the process by which new sea floor forms at mid ocean ridges?
as it spread away from a mid-ocean ridge, the sea floor carries with it a record or magnetic reversals. i hope this answer would be correct :) also, when the magma rises through fractures in the sea floor at the mid-ocean ridge, the magma cools and forms new rocks. this new rock takes place of the old rock and the old rock gets pulled away.
What are the 4 steps of seafloor spreading?
I'm not that sure since I am doing a science assignment on seafloor spreading but, I think I've got a pretty good grasp on 5 stepsMagma pushes up through the Earth's mantle and breaks through the crust.Magma flows outward in the ocean in all directions and hardens to form new ocean floor by the ridge.New ocean floor pushes the old floor away from the mid-ocean ridgeThe old floor then pushes the continents away from the ridgeLastly, the old ocean floor is forced under the continental plate, and melts back into magma.I'm not that sure but, I think I've got a pretty good grasp on 5 stepsMagma pushes up through the Earth's mantle and breaks through the crust.Magma flows outward in the ocean in all directions and hardens to form new ocean floor by the ridge.New ocean floor pushes the old floor away from the mid-ocean ridgeThe old floor then pushes the continents away from the ridgeLastly, the old ocean floor is forced under the continental plate, and melts back into magma.
What happens after magma erupts along mid ocean?
The magma spills over the ridge and pushes the old sea floor away toward a subduction zone where the old sea floor melts.
Are oceanic rocks billion years old?
No. Oceanic crust is recycled into the mantle through a process called subduction and new ocean floor is formed at mid-ocean ridges. None of the ocean floor is more than about 180 million years old. Some rocks on the continents are billions of years old.

What happens to the old ocean floor as the sea floor spreads?
As the sea floor spreads, the old ocean floor gets pushed out, which makes the plates move.
Why is the earth 4.6 billion years old but the oldest sea floor is only 180 millions years old?
Just as new sea floor forms at mid-ocean ridges, new sea floor is forced back into the mantle at abduction zones. The oldest seafloor is at east and west the edges of the Atlantic Ocean, dating to the breakup of Pangaea.
How old is the sea floor?
It varies from a maximum age of 200 million years to the newly created sea floor at the mid-ocean ridges.
Is the sea floor along the mid ocean ridge old or young?
Young, because it is being continually formed as the adjoining tectonic plates move apart.
Old ocean floor is destroyed and absorbed by the Earth and remelted beneath what?
When the old ocean floor is destroyed, it goes to Earth's mantle.
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.
Why doesn't our planet get larger from sea floor spreading?
As new oceanic crust forms at mid-ocean ridges, old oceanic crust is destroyed at subduction zones.
