What is a sand spilt?
A "sand spit" is an elongated line of sand (or sandbar) that usually extends parallel to the shore, connected to the mainland. If it grows high enough to survive tides, it can become a peninsula. If it is separated from the land after forming, it can become an offshore barrier island.
Why do you get a chain of islands?
Island chains are caused by undersea volcanoes on a fault line. As volcanoes erupt over time, enough igneous rock is deposited to form a mountain peak above water. Multiple undersea mountains along a fault that become high enough to become islands form an island chain.
What is island hopping in science?
Island skipping.

Why would a finch population that lives on an island have a higher rate of speciation that a finch population that lived in a large forest in north America?
A finch population on an island is more isolated than Êa finch population in a large forest. ÊThe gene pool of the island population would be more limited than the genetic possibilities of the finch population in the forest. ÊThe island finches would be more likely to pass on specialized genes than the forest finches. the island finches have more spatial isolation the island finches have more geographical isolation
How can a island become a seamount?
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.
