Does The Ocean Floor Old The Farther

You can t be without protective.

Does the ocean floor old the farther. As you move further away from the ridge the older the. As you progress removed from the mid oceanic ridges sediment thicknesses will on popular increace since the oceanic floor is older the extra desirable you get from spreading centres. The farther from the center of earth s mantle circulation so the pressure to the top. The rocks of the ocean floor gets older the farther they are away from the mid ocean ridge.

In the mid atlantic there is volcanic activity creating new crust. Not too many people have gone to the floor of the ocean as it requires special diving equipment since the water pressure is very high the farther down you go. Briefly explain why the ocean floor generally gets deeper the farther one travels from the ridge crest. So although the pacific ocean is much wider than the atlantic the oldest crust in the pacific found near the mariana trench is about the same age approximately 180 million years old as the oldest crust in the atlantic which occurs near the eastern coast of the united states.

Because of this correlation between age and subduction potential very little ocean floor is older than 125 million years and almost none of it is older than 200 million years. Continental shelf 300 feet continental slope 300 10 000 feet abyssal plain 10 000 feet abyssal hill 3 000 feet up from the abyssal plain seamount 6 000 feet. This graphic shows several ocean floor features on a scale from 0 35 000 feet below sea level. The age of the seafloor increases.

The ocean floor is like a giant magnetic tape recorder magnetic reversals showed that the oceanic crust is getting older away from the mid ocean ridges convective cells in the mantle drive plate movements. At the mid oceanic ridge there is a vertical upward pressure caused by the circulation of the earth s mantle. The subduction of cold dense slabs of oceanic lithosphere is the main driving force of plate motion.
