|They form by the earth's crust folds, cracks, and bends
going up because of the moving plates.
|Most of the underwater mountains form when the
continental plates come together. As the plates push together their ends
crumble together and form into mountains.
|At some places the continental and oceanic plates collide
because the continental rock is lighter than seafloor rocks. The
continental plates move upward and over the ocean plate.
|Underwater mountains donít only form at the boundaries
and the plates. Some of them form at the where pressure from moving at the
boundaries, of plates.
