Guyot

====A guyot is an isolated underwater volcanic mountain, also called a seamount. It has a flat top over 200 meters below the sea's surface. Their flatness is due to erosion by winds, waves, and atmospheric processes. Guyots are most commonly found in the Pacific Ocean. Usually, to be considered a guyot or tablemount, they must stand at least 900 meters (3000 feet) tall. Seamounts are useful because they provide data on movements of the tectonic plates on which they lay on. ==== ==== As the mid-ocean ridges spread apart, the guyots move with them, thus continually sinking deeper into the depths of the ocean. Thus, the greater amount of time that passes, the deeper the guyots become. ==== ==== Although guyots can be hundreds of millions of years old, there have been some recently discovered guyots that were only formed within the last 1 million years. (i.e. Bowie Seamount in Canada) ====


====Guyots were first recognized by Harry Hess in 1965 who collected data using echo-sounding equipment on a ship he commanded during World War II. He named his discovery after a Swiss-American geographer and geologist named Arnold Guyot. ====
