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.
They are not.
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.
The closer a rock is to a mid-ocean ridge, the younger they are.
The 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.
No. The rocks of the ocean floor gets older the farther they are away from the mid-ocean ridge.
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.
Silicates make up close to 95 percent of the rocks in the Earth's crust
very close to the sun .they are made up of rocks .
silicates
Solid- Close together Liquid- Bit farther apart Gas- Far apart

The opposite of "these" (close at hand) is those(relatively farther away).
yes he had a younger brother

San Francisco, California is farther west, actually quite close to the Pacific Ocean.
No. Sedimentary rocks form relatively close to the surface. No rocks that we have access to come from the planet's center.
