Coastal Landscapes – Processes

The Costal Zone

The coastal zone is a narrow stretch between the land and the sea. The sea, land and air constantly change its shape and form.

The United Kingdom has approximately 17,820 km of coastline and there are many different types of coastal environment:

  • cliffs
  • beaches
  • sand dunes
  • salt marshes
  • ports/harbours
  • seaside resorts

Three key processes take place in the coastal zone:

  • Erosion – waves can erode the coastline in a similar way to the water in rivers. This usually occurs when the sea takes lots of energy from the power of destructive waves.
  • Transportation – the movement of eroded material up and down, and along the coast.
  • Deposition – when the sea loses energy, it drops the sand, rock particles and pebbles that it has been carrying, depositing them.Waves 3

Four key factors affect the erosion of the coastline:

  • Rock type – chalks and limestone can form steep cliffs, whereas clays and softer rock form large bays
  • Rock structure – a discordant coastline, where rocks are at an angle to the edge of the coastline, will erode at different rates.

People tend to put there boats in bays this is because the waves won’t be as strong this is because of wave refraction. If you have cliffs on a beach you will se

how much they erode you can tend big holes in them and over time that can make a portion of the cliff fall.

The power of waves is one of the most important things when it comes to coastal erosion.

How I Feel

Today I am feeling great I feel like so much has lifted off my shoulders and I am still really happy that I am going to visit my dad. I am still a bit sad that I didn’t get to go to Turkey with him but I guess it wasn’t ment to be. I am looking forward for our next trip to whatever country.

I hope you enjoyed todays post and share if you did and like if you really liked it 🙂
