In this episode, we discuss headlands, bays, caves, arches & stacks.

Coastal landscapes featuring headlands and bays emerge where alternating bands of hard and soft rock meet the sea.

Softer rock erodes more rapidly, forming inward curves known as bays, while the more resistant hard rock juts out as headlands.

Erosion of headlands along lines of weakness can lead to the formation of caves through widening cracks.

If a cave erodes through a headland, an arch is created.

Eventually, the collapse of an arch's roof due to gravity leaves behind a solitary pillar of rock called a stack.
