Bookmark or Share- Seamount - WikipediaA 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.
- Factsheet: How Do Seamounts Form? - NOAA Ocean ExplorationSeamounts 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.
- What is a seamount? - NOAA Ocean ExplorationA 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.
- Seamounts - Woods Hole Oceanographic InstitutionSeamounts are underwater mountains that rise hundreds or thousands of feet from the seafloor. They are generally extinct volcanoes that, while active, created piles of lava that sometimes break the ocean surface.
