Erosional and Depositional Processes

Headlands

Where there is harder, more resistant rock (e.g. granite), a headland will be formed. 

Bays

Bays are formed from softer, less resistant rock. The rock (e.g. clay) is eroded by wave action and an inlet is formed. This means that on either side of the bay there will be a headland.

A concordant coastline is when the coast runs parallel to the sea, producing  relatively straight coastlines

A discordant coastline is when the coast runs at right angles to the sea, often producing headlands and bays. 

Rock Structure

This relates to the physical characteristics of the rock…
