Seamount - Wikipedia
WebA seamount is a large submarine landform that rises from the ocean floor without reaching the water surface ( sea level ), and thus is not an island, islet, or cliff -rock. Seamounts are typically formed from extinct volcanoes that rise abruptly and are usually found rising from the seafloor to 1,000–4,000 m (3,300–13,100 ft) in height.
What is a seamount? - NOAA Ocean Exploration
WebA seamount is an underwater mountain with steep sides rising from the seafloor. This ~4,200-meter (~13,800-foot) high seamount, dubbed "Kahalewai," was mapped during the Mountains in the Deep: Exploring the Central Pacific Basin expedition and was found to be almost 1,000 meters taller than previously thought.

Webby Smithsonian Ocean Team. Thousands of seamounts—most of them undersea volcanoes—tower above the muddy seafloor. They provide something hard to come by in the deep ocean: a solid surface to cling to. Corals, sponges, and other marine animals attach themselves in dense colonies to seamount slopes.
WebSeamounts are underwater volcanoes found in every ocean. They can form in different ways, but most are remnants of extinct volcanoes. Seamounts are generally found at mid-tectonic plate regions, called hotspots, and near the boundaries of tectonic plates. Seamount Formation at Volcanic Hotspots.
WebWhat is a Seamount? Most seamounts are remnants of extinct volcanoes, while others are actively erupting and growing. Typically, they are cone shaped, but often have other prominent features such as craters and linear ridges. One type, called a guyot (gē’-ō), has a large, flat summit.
