How do islands become seamounts?

At mid-ocean ridges, plates are spreading apart and magma rises to fill the gaps. Near subduction zones, plates collide, forcing ocean crust down toward Earth’s hot interior, where this crustal material melts, forming magma that rises buoyantly back to the surface and erupts to create volcanoes and seamounts.

What is the geologic history of Hawaii?

A hotspot beneath the Pacific Plate created Hawaii’s volcanic islands. As this hotspot has remained stationary over the last 40 million years, the plate above has drifted west-northwest at a rate of three and a half inches per year. Over time, the hotspot resulted in 82 volcanoes emerging to form the Hawaiian Ridge.
