It varies widely depending on the type of volcano and the depth of the ocean in the area. The volcanoes that formed the Hawaiian islands took hundreds of thousands of years to form. They are shield volcanoes that merged from the deep ocean floor.
Anak Krakatau, a statovolcano, emerged in shallower waters in 1927 after the destruction of its predecessor, Krakatoa, in 1883. This is a time span of only 44 years.

Why Hawaii is made of volcanoes due to?
The Hawaiian Islands formed over a hotspot in the Pacific Ocean, where magma formed a column and rose through the Earth's crust, causing volcanic activity. The hotspot stays fixed as the Earth's plates move over it, which is why, currently, no island but the Big Island experiences volcanic eruptions.
What is a volcanic type of mountain?
A volcanic mountain is a mountain formed by volcanic action. It is usually cone-shaped with a depression on top, which is where the crater is, or was, in the case of extinct volcanoes. Volcanic mountains rise up as a result of movement of the tectonic plates beneath the earth's crust, which allow the magma to rise up from the mantle underneath.Ancient volcanic mountains may have misshapen and craggy-looking upper portions. These are the volcanic plugs left behind after centuries of erosion have worn away the soil from around the plug.a volcanic mountain is a mountain that is able to erupt.
Where is barcena the volcano?
Barcena Volcano is located on the island of San Benedicto in the Revillagigedo Islands, Mexico. It is one of the active volcanoes in the region and is part of a volcanic chain known as the East Pacific Rise. The Revillagigedo Islands are a UNESCO World Heritage Site due to their unique and diverse ecosystems.
How was the island of Kilauea created?
There is a chain of over 129 submerged seamounts, coral atolls, extinct volcanoes, and active volcanoes all generated by the same hotspot mantle plume as the pacific plate slowly slid over it. The Hawaiian Islands are just the most recently formed series of extinct and active volcanoes in this chain.

How does an island change?
An island can change through natural processes such as erosion, volcanic activity, and sea level rise. Human activities such as deforestation, development, and pollution can also significantly alter an island's landscape and ecosystem. These changes can impact the biodiversity, coastal areas, and overall sustainability of the island.

When did Kangaroo Island separate from the Australian mainland?
Kangaroo Island was separated from mainland Australia by a rise in sea level about 9,000 years ago (from Wikipedia)
What is the name of the large island located on the Reykjanes ridge?
The large island located on the Reykjanes Ridge is called Iceland. It is situated at the convergence of the Eurasian and North American tectonic plates, giving rise to its unique geological features like geysers and volcanic activity.
What kind of mountain is formed when magma rise to the surface and erupts?
Volcanic mountains
When will magma rise to earths surface?
During a volcanic eruption or on a constructive boundary
Why an island that is form for a volcano that is erupting doesn't get bigger?
Because most of the lava goes underwater and takes years for the lava to rise up to make an island bigger.
How can an island become a seamount?
Yes, a sea mount can become a volcanic island because they are individual mountains of volcanic material. They form where magma pushes its way through or between tectonic plates. If a sea mount builds up above sea level, it becomes a volcanic island.
