guyot - Science Definition
A flat-topped, extinct submarine volcano having an elevation of over 1,000 m (3,280 ft) above the ocean floor. Guyots are thought to form as volcanos in sea-floor spreading zones and to become extinct as they move away from the spreading zones through plate tectonic forces. Their flat tops are believed to form by the erosional action of waves when they initially project above sea level.
