You can find the seafloor spreading in the middle of the Atlantic Ocean. It is pushing Europe and Africa away from North and South America. You can go to Iceland and stand on the place where the spreading seafloor comes onto land. There, you can put one foot on Europe and one foot on America. It would be quite a while before your feet became another inch apart.
in a subduction trench, because of Harry Hess' theory of sea floor spreading. Meaning that the rock is formed new at the mid-ocean ridge, and moved out towards the coasts into a subduction zone years and years later.
people here are stupid , really the answer is not hi
Yes, Harry Hess proposed the theory of seafloor spreading and the existence of mid-ocean ridges during the 1960s. His work significantly contributed to the development of the theory of plate tectonics.
At a mid-ocean ridge, you would expect to find a symmetrical pattern of striping on either side of the ridge. This pattern is created by the process of seafloor spreading, where new oceanic crust is formed as magma rises and solidifies at the ridge. As the tectonic plates move apart, magnetic minerals in the newly formed rock align with the Earth's magnetic field, resulting in alternating bands of normal and reversed magnetic polarity. This pattern is mirrored on both sides of the ridge, providing evidence for the age of the oceanic crust and the history of geomagnetic reversals.
At a mid-ocean ridge, you would expect to find a symmetrical pattern of magnetic striping on either side of the ridge. This pattern results from the periodic reversal of Earth's magnetic field, which causes new basaltic rock formed at the ridge to record the current magnetic orientation as it cools. As tectonic plates move apart, these magnetic stripes mirror each other on both sides of the ridge, providing evidence for seafloor spreading. The age of the stripes increases with distance from the ridge, supporting the theory of plate tectonics.

dumb question. don't want to write it all

Because of erosion, or because of sea floor spreading. Sea floor spreading would be the cause of it because it moves the rock to a submerging area and the mantle's hot "body" melts it. Now erosion would be part of it because it erodes the rock away, leaving sand or dirt from that rock. If they were looking for ancient sand, then they would most definitely find it.
I don't have evidence, but oceanographers have evidence. In mid ocean ridges, more and more molten rocks come up from the surface and cool down. As a result, the rocks already there get pushed away. We did find molten rock coming up from the mantle. Also, when scientist carbon dated the rocks on mid ocean ridges, they found that the farther you go outward, the older the rock. That's another sign. There's more but i can't think of it now. Hope this helps.

hhjhh
you would find magma and lava because the rocks cousin them to turninto lava that is what you would find at the core of the earth
in the depths of the oceanic crust floor.
