The wearing away of rocks at different rates because they have different resistance to erosion.

The erosion of different rocks at different rates because they have different resistance to erosion.

Where alternating bands of harder and softer rock are exposed to the sea, they retreat at different rates. This is called differential erosion.

Link named features to processes: High Force → contrasting rock resistance → differential erosion → waterfall retreat and gorge formation.
