Zealandia is a microcontinent off Australia that’s nearly fully underwater—except for the island nation of New Zealand. Many islands, comparable to Easter Island in the South Pacific Ocean, are hundreds of kilometers from the closest mainland. The Galapagos ecosystems, both terrestrial and marine, are a example of human affect on islands. Because of isolation , many islands have additionally been dwelling to some of the world’s most unusual and fascinating wildlife. Continental islands may form through the weathering and erosion of a hyperlink of land that after connected an island to the mainland.
Barrier islands may also be coral islands, created from billions of tiny coral exoskeleton s. Barrier islands are separated from shore by a lagoon or a sound.
