The Main Landforms Associated With These Processes (Changing coastal environments)
Overview
A coastline is a record of a long argument between the sea and the rock. Where the rock is weak the sea wins, carving bays, caves, arches and stacks. Where waves run out of energy they put material down, building beaches, spits, bars and dunes. The shape of the land, hard headland or soft bay, sand spit or chalk stack, tells you which side is winning and why.
This lesson works through the coast's two families of landform: the features of erosion (headlands and bays, cliffs, wave-cut platforms, caves, arches, stacks and stumps) and the features of deposition (beaches, spits, bars and sand dunes). You will also learn how the layout of hard and soft rock creates discordant and concordant coastlines.
Objectives
- The characteristics and formation of landforms: headlands, bays, cliffs, wave-cut platforms, caves, arches, stacks, stumps, beaches, spits, bars, sand dunes.
- The formation and characteristics of discordant and concordant coastlines.
