- Oceanic islands: These rise from the ocean floor and were never part of a continent.
- Coral islands: These are formed from the buildup of coral reefs.
- Tidal islands: These are landmasses connected to the mainland by a causeway that is submerged at high tide.
- Artificial islands: These are man-made islands created for various purposes.
