- Rias:
- Formed where river valleys are partially submerged.
- Gentle, long- and cross-profiles.
- Wide and deep at their mouth.
- Fjords:
- Drowned glacial valleys rather than drowned river valleys.
- Straight and narrow with steep sides.
- Shallow mouth formed by deposition of material.
- Dalmatian coasts:
- In areas where valleys lie parallel to the coast, an increase in sea level forms a dalmatian coastline.
- Valleys are flooded, leaving islands parallel to the coastline.
- Processes create and alter landforms and landscapes over time:
- Individual landforms combine to form landscapes.
- Processes operating in coastal systems can create new landforms or change existing landforms:
- A change in one factor can lead to changes in others.
- Relict landforms can still experience coastal processes.
- Coastal landscapes are therefore often made up of a mixture of active and relict landforms that reflect different periods of change.
- Changes occur over a range of spatial scales and temporal scales.
