Why are the rocks close to mid-ocean ridge younger than the ones that are farther away?
Midocean ridges are areas where continents broke apart. Midocean ridges are closest to the landmasses in younger oceans. One example where a midocean ridge intersected a landmass is the Arabian sea, which was formed by the pulling apart of the Arabian Peninsula and Africa.
Midocean Ridge - Underwater Mountains! A mountain chain on the ocean floor that forms where tectonic plates pull apart.
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
Is the oceanic crust near the mid ocean ridge younger than oceanic crust farther away from the ridge?
No. The rocks of the ocean floor gets older the farther they are away from the mid-ocean ridge.
Rising molten basaltic rock from the top of the mantle fills the crack at the midocean ridge and solidifies, preventing it from closing again.
hit the books!!
haha i really dont know
The closer a rock is to a mid-ocean ridge, the younger they are.
At the highest parts of the midocean ridge.
The closer the sediment is to the mid-ocean ridge, the younger it is. The oldest bedrock is found the farthest away from it.
the ages of the rocks become increasingly older in samples obtained farther from the ridge and the younger had just come out the ridge.
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.
The evidence that supports Wegner's hypothesis is that in 1947 , a group of scientisits noticed two things about the Mid- Atlantic Ridge. The first thing that the scientists noticed was the sediment that covers the sea floor is thinner and younger closer to a ridge than it is farther from a ridge. Second, scientists learned that the ocean floor is very young. Radiometric dating shows that the sea floor closer to the mid-ocean ridge… Read More
They measure how far away the rock is from the mid-ocean ridge. The farther, the older.
A convection current causes magma to rise at the midocean ridge and pushes the plates apart.
One of the midocean ridges is, but others are in other oceans, seas, and bays.
Is the oceanic crust near the mid-ocean ridge younger or older than the oceanic crust farther away from the ridge?
It is younger because the plates there pull apart, causing a new sea floor to form. When a hotspot is involved, it will push away the old sea floor to make room for the new one.

What is the difference between a rift valley and a mid ocean ridge and what kinds of boundaries do they form at?
a rift valleyis a dip in the ocean floor a mid ocean ridge is a mountain chain formed on the ocean floor . Rift valley - divergent boundary MidOcean Ridge Convergent Boundary
It is because the sediments have had more time to accumulate. Oceanic crust is older the farther it is away from the ridge, where new crust is formed.
friction - convection currents in the mantle drag the plates away from the hot rising zone below the ridge gravity - gravity pulls down on the cold dense plate being subducted under the continent, dragging the plate away from the ridge
It's Age! are you kidding me? Ha Ha I have the same stupid question on my science paper. the crossword right? its age!
The midocean ridges are the spreading centers where the plates are moving apart. The seamounts are extinct volcanos produced as the plate passed over a mantle hotspot.
How does evidence that rocks farther from a ridge are older than rocks closer to the ridge support the idea of sea floor spreading?
Harry Hess was mapping the floor of the ocean when he found a mountain range in the middle of the ocean. He found that the land nearest to the ridge was younger compared to the fact that the farther away land was from the ridge, the older it dated. He used this to find that the mountain ridge was creating new land and pushing aside the old land.
It gets younger.
Oceanic crust that was farther away from a mid-ocean ridge was older that crust closer to the ridge
Its oceanic crust
oceanic crust that was farther away from a mid-ocean ridge was older than crust closer to the ridge
is that the mid-ocean is close to the ridge ans to the fault
Actually, the rock taken the farthest away from the ridge is older.
it is older
The sea floor gets older as you get farther from the mid-ocean ridge.
No farther away
Younger. New rock is formed at the MOR.
No, actually its the farther it goes from the ridge the older and the thicker it gets.
How did scientists discover that rocks farther away from the mid ocean ridge were older than the ones closer to the mid ocean ridge?
I don't believe that is possible to figure out
As one moves farther away from an ocean ridge, the age of the rocks and the seafloor increases. This process is called seafloor spreading.
right now its 1.25
it is known as sea floor spreading. this is when the oceanic plates diverge or move apart which causes the magma from the mantle to rise forming new sea floor.
Because it is
Iceland sits astraddle the mid-Atlantic ridge.
It gets older.
it is a REEF
How did scientists discover that rocks farther away from the mid-ocean ridge were older than those near it?
i never know
farther. the mid Atlantic ridge is a DIVERGENT BOUNDARY it's getting pushed in opposite directions
