  1. There are two main types of oceanic islands. Both are created by geological disturbances below the surface of the ocean.

    Volcanic islands are formed when volcanoes on the ocean floor rise above the surface of the ocean. The Hawaiian Islands are a well-known example of this phenomenon.

    Coral islands are created when coral accumulates on top of volcanic rocks in the ocean. This type of island has stopped "growing" and is very gradually sinking back into the sea. The Solomon and Marianna Islands are examples of coral islands.
