Year 13 - Coastal Processes and Landforms

A quick recap this morning of the main processes affecting the coastline (various processes of erosion, sub-aerial processes...), how geology affects rates of erosion, and then various erosional and depositional landforms that you need to be familiar with:

- headlands and bays
- caves, blowholes, geos, arches, stacks, stumps
- wave-cut notches and platforms

- beaches (storm beaches, berms, ridges, runnels, cusps, ripples)
- spits, bars and tombolos

Some nice sketch maps of the key landforms of the Holderness Coast and the Jurassic Coast, a discussion about whether Chesil Beach was a bar or a tombolo, and the some short-answer exam questions - don't forget that if you have time before next Wednesday, that it would be useful for you to have had a go at marking your questions.

My photos that we looked at of the Flamborough area and of the Jurassic Coast are all on Flickr - not brilliant pictures, but should serve as a bit of a reminder of the landforms and features that we talked about this morning.
