Why are the Rock's close to a mid-ocean ridge younger than the ones that are farther away?

∙ 6y ago
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.

For instance, one may go to any active volcano and find rock which is hours old.
However, generally, the sea floor is relatively young rock which spreads from huge faults under the ocean. This sea floor eventually gets transported to a boundary and heaps up into mountains which break the surface.
Thus the concept that sea floor rock is younger than the continental surface rock.

∙ 13y agoThe middle of the ocean is usually host to what is called a mid-ocean-ridge. This is where magma from inside the earth rises up and crystallizes.

How did scientists determine the difference in the age of rocks near mid ocean ridges from those farther away from ridges?
Good question: Geologist use these methods to determine the ages of rocks. The absolute age of the rock and relative age of the rock. Now because the mid ocean ridges are place of divergent where plates move apart, the rock farther away from the ridges are older than the younger ones that are just form close to the ride. This is called relative dating. The absolute dating use Isotopes and radiometric dating meaning they have to have a hand sample to determine this. But I think the best method here for situation like this is the Relative ages of the rocks.

Is Reno Nevada or San Francisco California farther west?
San Francisco, California is farther west, actually quite close to the Pacific Ocean.
Do sedimentary rocks come from the center of the earth?
No. Sedimentary rocks form relatively close to the surface. No rocks that we have access to come from the planet's center.
