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.
How could an island become a seamount?
An island can become a seamount through the process of erosion and subsidence. Over time, natural forces like wave action and weather can erode the land above sea level, while geological processes may cause the island to sink or subside due to tectonic activity. As the island erodes and sinks, its peak may eventually become submerged, transforming it into a seamount—a submerged mountain on the ocean floor.
Which island is a seamount in Hawaiian?
In Hawaii, the term "seamount" typically refers to underwater mountains that rise from the ocean floor, and one prominent example is the island of Loihi. Loihi is an active seamount located southeast of the Big Island of Hawaii and is considered the newest addition to the Hawaiian island chain. It is still submerged and has not yet emerged above sea level, but it is expected to eventually become an island as volcanic activity continues.
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.
