Brief Explanations:

At mid - ocean ridges, where there are cracks in the oceanic crust, magma (molten rock) rises from the mantle. Dense crust and continental crust do not rise from such cracks. Pillow - shaped rocks are formed when the molten rock cools underwater, but they do not rise from the cracks themselves; it is the molten rock that rises first.

Answer:

molten rock
