A submarine table-mountain, found especially in the Pacific. It is thought that guyots originate as volcanic islands associated with mid-ocean ridges. They rise approximately 1,000 m (3,300 ft), with tops about 2.5 km (1.5 miles) below sea level. Wave erosion reduces the island, and sea-floor spreading causes the guyot to be further submerged.
