Why are the rocks close to 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.

What are the rocks close to a mid ocean ridge younger than the ones that are farther away?
no
Where do midocean ridges intersect the landmasses?
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.
Is oceanic crust near the mid ocean ridge younger than oceanic crust farther away from the ridge?
haha i really dont know
Do Ocean sediments become younger or older away from midocean ridges?
Older, as it moves away from the mid-ocean ridge the sediment gets thicker and older
Oceanic crust near the mid ocean ridge is younger than oceanic crust farther away from the ridge?
hit the books!!
Is oceanic crust near the mid ocean ridge younger than oceanic crust farther from the ridge?
haha i really dont know
What does the sediment the is closer to mid ocean ridge compare to sediment that is farther away?
The closer the sediment is to the mid-ocean ridge, the younger it is. The oldest bedrock is found the farthest away from it.
How the age of the rocks on the ocean floor support the theory of the seafloor spreading?
the ages of the rocks become increasingly older in samples obtained farther from the ridge and the younger had just come out the ridge.

Summarize the evidence that supports wegner's hypothesis?
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 are younger, than the ones farther.
How do scientists explain older and younger rock placement on the ocean floor?
They measure how far away the rock is from the mid-ocean ridge. The farther, the older.
