What are island made out of?

Answer 1

The methods by which islands are formed are:

• Continental Islands, which are the parts of a continental shelf which rise above the water.
• Oceanic Islands, which are formed by volcanic action; they are found lined along converging oceanic plate boundaries, associated with sea floor movement.
• Coral Islands, formed like coral reefs from living creatures; when a reef formation is large enough, it will protrude above the water.
• Barrier Islands, found near shallow coast lines; they are composed of unconsolidated sediment, usually sand, which the currents have compiled over centuries.

Answer 2

Islands are typically made of a combination of rock, sand, coral, and organic materials such as vegetation and animal remains. They can also be formed from volcanic activity, where lava solidifies to create new land masses. Erosion, deposits from rivers or glaciers, and tectonic plate movements can also contribute to the formation of islands.
