volcanos
Erosion by both wind and water.
no people should not build on barrier islands because it causes soil erosion... and soil erosion is bad :) hahaha be an erosion freee world
Wind and water erosion, but don't worry that is a very, very slow process.
it is difficult for geographers to determine the number of islands in oceaina because it is constantly changing. Erosion causes some islands to vanish while other forces create new islands
Generally islands are simply the top portion of volcanos that grow from the seabed to above sea level.
Destiny Islands is the home of Sora, Riku, and Kairi in Kingdom Hearts. It is also the home of the Paopu Fruit, a yellow star-shaped fruit that, if shared between two people, causes destinies to be forever intertwined. Destiny Islands is overrun by Heartless in the first Kingdom Hearts, which starts Sora on his quest as the Keyblade Master.
There is a 'Hot-spot' in the mantle underneath the crust near the Hawaiian islands, it causes the magma to bubble up through fissures in the sea floor and eventually create new islands. this is how they were formed. for more info look at mantle convection.
Hot spots are a concentrated area of the upwelling of magma. This causes mantle plumes above these hotspots. The Hawaiian Islands are an example of this occurence, as the hotspot forms multiple volcanic islands in a neat row when the plate above it moves over it.
Barrier islands are not parallel to California's coastline because of the tectonic activity along the San Andreas Fault. The movement of tectonic plates causes the coastline to be irregular with headlands and bays, making it difficult for barrier islands to form in a parallel manner. Additionally, the wave energy and sediment transport patterns along the California coast also contribute to the lack of parallel barrier islands.
The Hawaiian islands are not the result of plate techtonics, they are the result of volcanic activity relating to a particular hot spot in the Earth's mantle, from which a plume of hot magma rises upward and causes volcanic eruptions.
The chain of islands is the = Aleutian Islands =
The Andaman and Nicobar Islands in the east and The Lakshadweep Islands in the west.
