- Different ways of classifying coasts
- Primary coasts
- Land based processes, such as deposition from rivers, or coastal land formed from lava flows.
- Secondary coasts
- Marine erosion or depositional processes from the sea.
- Emergent coastlines
- When the coast is rising relative to the sea level, due to tectonic uplift, or the elastic rebound theory, responding to the Ice Age and its features.
- Submergent coastlines
- These coastlines are being flooded by the sea, due to a rise in relative sea level on a global scale. it could also be a result of subsiding land on a local level.
- Tidal range
- microtidal- where the tidal range does not exceed 2m.
- mesotidal- where the tidal range is between 2-4m.
- macrotidal- where the tidal range exceeds 4m.
- wave energy - the wave energy can influence the type of coast that is present.
