How Do Seamounts Form - Plate tectonics and marine geology. Learn how seamounts form from different types of volcanic activity in the deep ocean. Thousands of seamounts—most of them undersea volcanoes—tower above the muddy seafloor. Introduction to oceanography (webb) 4: In plan, seamounts tend to be elliptical or elongate, possibly because the lavas are extruded from linear rifts in the seafloor. Find out how seamounts are related to tectonic plates,.
