Submergent coastlines

• Rias

  • A river valley at the coast that has been inundated by the sea as relative sea level has risen, resulting in a ‘drowned valley’
  • For example, the south coast of Devon (Dartmouth) and Cornwall (Falmouth)
• Fjords

  • A glaciated valley at the coast that has been inundated by the sea.
  • Has steeper rising walls, a straighter long file and is deeper than a ria due to glaciers over-deepening the valley
  • For example, the west coast of Norway
