How are seamounts related to guyots an islands?
Seamounts and Guyots are volcanoes that have built up from the ocean floor, sometimes to sea level or above. Guyots are seamounts that have built above sea level. Erosion by waves destroyed the top of the seamount resulting in a flattened shape. Seamounts generally rise more than 1,000 meters above the sea floor, often forming islands. When the action of plate tectonics moves a seamount-formed island away from the mid-ocean ridge, the ocean crust sinks, pulling the island beneath the surface. These submerged, often flat-topped, seamounts are called guyots.
