Continental islands.
Barrier island.
  • ´Continental islands, which occur due to flooding and erosion of land on the edge of a large continent.
  • Volcanic islands, which are formed when volcanoes deep in the ocean rise above the water's surface.
  • Coral islands, which are large collections of coral atop rock (usually volcanic) in the ocean.
  • Alluvial islands, which are formed by the outward flow of water depositing silt and gravel at the mouth of a river.
  • Barrier islands, which are formed by waves depositing sand on the shallow ocean bottom as they crash on the shoreline.
