An island can become a seamount only if there is native and active volcanic activity that is able to raise the landmass sufficiently above sealevel.

How can seamount become an island?
An island can become a seamount only if there is native and active volcanic activity that is able to raise the landmass sufficiently above sealevel.
What is the relationship between seamount and volcanic island?
A seamount is an underwater mountain formed by volcanic activity, while a volcanic island is a landmass that rises above the ocean's surface due to volcanic eruptions. Seamounts can eventually grow to become volcanic islands if the volcanic activity continues and brings the seamount above the water level.
What is it called when a seamount rises above sea level?
Island
What do you call an underwater volcano?
An underwater volcano is called a submarine volcano.
What kind of mountains form from hot spots?
Hot spot volcanos. As these age they can become island chains and eventually subsurface seamount arcs if the hot spot is in the ocean.
How does erosion form landforms?
Island Seamount
Is Bermuda a limestone island?
It is a limestone cap on the tip of a volcanic Seamount (underwater mountain).
What is the physical difference between a seamount and a volcanic island?
A seamount is a submerged mountain rising from the ocean floor, while a volcanic island is a mountain formed above sea level by volcanic activity. Seamounts may not breach the surface, while volcanic islands are visible and can support terrestrial life.
What is the name of the new Hawaiian island?
The Lo'ihi Seamount is 22 miles off the southeast coast of the Big Island and has been actively growing for 400,000 years and should become an island in between 10,000 and 100,000 years.
What is a mountain on the ocean floor that can turn into volcanic islands?
A seamount is a mountain under the ocean that can eventually rise above the sea surface and become a volcanic island through volcanic activity. Over time, as lava continues to build up on the seamount, it can breach the water's surface, forming a new landmass.
What tectonic plate is forming the new island of Loihi?
The new island of Loihi is forming on the Pacific Plate. It is a seamount located south of the Big Island of Hawaii, and it is part of the Hawaiian-Emperor seamount chain. The Pacific Plate is moving northwestward over a hotspot, which is causing volcanic activity that is building the island.
What is the process of a seamount?
A seamount is formed by volcanic activity beneath the ocean's surface, where magma rises and solidifies to create a mountain-like structure. Over time, the seamount can grow larger through continued volcanic eruptions or tectonic plate movement. As the seamount ages, it may eventually become extinct and eroded by ocean currents, forming a flat-topped seamount called a guyot.
