Question

How are islands formed?

Answer 1

Step-by-step explanation:

As volcanoes erupt, they build up layers of lava that may eventually break the water's surface. When the tops of the volcanoes appear above the water, an island is formed. While the volcano is still beneath the ocean surface, it is called a seamount. Oceanic islands can form from different types of volcanoes.

Answer 2

Answer: they can be formed in many ways.

Step-by-step explanation:

The main way though is by tectonic plates. When they move, they can create cracks in the earth which causes magma to flow out of, which in turn slowly builds up over time eventually breaking the surface of an ocean or sea and finally becoming lush with greenery.
