Definition. A guyot is an underwater volcanic mountain that has a flat top, formed from erosion and sedimentation. These unique structures are typically found in the deep ocean and represent remnants of once-active volcanoes that have eroded over time, highlighting the dynamic nature of oceanic geological processes.

A guyot is a flat-topped submarine mountain, or seamount, that once emerged above sea level as a volcanic island, and then resubmerged when volcanic activity ceased. Erosion by wave activity during submergence creates the characteristic flat-topped profile of a guyot.
