Description
Browse peninsula and island types by origin, traits, and places.
CoastForms helps geography enthusiasts explore how peninsulas and islands form.
A peninsula is land with water on three sides and a link to a larger land mass. In this app you can review three origin groups: tectonic peninsulas shaped by crustal movement, erosional peninsulas shaped by coastal wear and sediment change, and depositional peninsulas shaped by sediment buildup.
An island is land with water on all sides. You can review four origin groups: continental islands separated from mainland settings, volcanic islands built by eruptions, coral islands linked to reef growth, and alluvial islands formed by river sediment.
Each type page shows a formation path, typical traits, and representative places. You can also open a side-by-side comparison, a short glossary, example places, and local notes stored on your device.
CoastForms is a concise reference for building a clear picture of coastal landform origins. It is not a field survey substitute.
