Types of islands. Artwork looking below the sea (which has been removed) to show types of volcanic islands. At upper right a large volcanic island towers out of the sea,formed by an underwater volcano that grew in height with each eruption until it broke through the surface of the sea. Plants (green) have started to colonise that island. At lower centre,erosions of a volcanic island,and the collapse of the central portion,has allowed corals to form the bedrock for the ring of land seen here,a coral atoll. The trench at left marks the edge of the continental shelf,and sediment deposits from a river are seen at centre left. See E680/207-209 for a set of images on this topic | |
