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.
