How do the sediments on the ocean floor vary in relation to an ocean ridge?
Sediments become thicker away from the mid ocean ridge. This is because the oceanic crust away from the mid ocean ridge is older than the crust close to it, so sediment has had more time to accumulate.
How does the age of seafloor sediments change with increasing distance from the ocean range?
At ocean spreading ridges, new oceanic crust is formed. The magma that forms this new crust emerges from the ridge and pushes the pre-existing rocks away from the ridge laterally. This results in a strip of new rock cutting through the older rock. As formation of the crust continues, the older rocks will be pushed further away from the ridge, while younger, newly produced rocks will occupy the area closest to the ridge.
Does the fact that ocean crust is older the farther away it is from an ocean ridge support the theory of plate tectonics?
Yes. New ocean crust is being formed at the mid ocean ridges (MORs) resulting in the older crust being pushed farther away, moving the plates towards a subduction zone. MORs divide 2 plates.
What ocean floor features are associated with areas where oceanic crust is broken down?
The mid ocean ridge is the area of the ocean floor that is associated with the breaking down of the oceanic crust. This area is known for seafloor spreading.
As oceanic crust moves away from the mid ocean ridge it cools and becomes more dense?
As the ocean crust gets older, its density increases. This has helped the continents to stay a float on the earths upper mantle for over a billion years.
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
Is oceanic crust near the mid-ocean ridge older thean oceanic crust farther away from the ridge?
Its oceanic crust
What evidence proved the ocean floor was moving?
oceanic crust that was farther away from a mid-ocean ridge was older than crust closer to the ridge
How do the sediments on the ocean floor vary in relation to an ocean ridge?
Sediments become thicker away from the mid ocean ridge. This is because the oceanic crust away from the mid ocean ridge is older than the crust close to it, so sediment has had more time to accumulate.
Why is the oldest seafloor crust found farthest from a mid-ocean ridge?
because the older crust is pushed out by the newer crust that is forming
Is Older oceanic crust found at the center of mid-ocean ridge?
No farther away

Is oceanic crust near a mid ocean ridge older than oceanic crust far away?
Sorry, you have it entirely reversed.
As distance from the mid atlantic ridge increases what change in the age of the sea floor is observed?
1. Divergent plate boundaries. The uplift of magma at the mid-ocean ridge is pushing the two plates apart. 2. The sea floor is older the further away from the mid-ocean ridge. (i.e. New crust is being formed at the mid -ocean ridge and pushing the older crust away. 3. 1 km = 100,000 cm / 3 per yr. = 33,333 years 4. rift zones, pillow basalts, black smokers, etc.
How does the age of seafloor bedrock vary with distance from a mid-ocean ridge?
The further from the ridge, the older the oceanic crustal rock.
Is ocean crust formed at a mid ocean ridge?
Yes, the process that creates oceanic crust on a mid-ocean ridge is called "seafloor spreading". seafloor spreading creates a new oceanic crust that forms on the mid-ocean ridge.
How can the ocean crust be different ages?
On geologic time scales, new oceanic crust is constantly being formed ad mid-ocean ridges while older crust is destroyed at subduction zones. The crust forms at the ridge and is carried away by the movement of the plate as new crust forms to take its place. The oceanic crust is youngest new a mid ocean ridge and oldest far away from it.
