Coastal Landforms - Erosion
crack
A crack will form in the headland due to erosion. A weakness in the headland is exploited. This is because of wave refraction
First
cave
A cave is a hollow place in the ground
As the crack widens, a cave is created as more erosion occurs.
caves are found along coasts around the world.
Second
stack
Fourth
Eventually, the roof of the arch collapses due to it being too heavy to support
A stack or sea stack is a geological landform consisting of a steep and often vertical column or columns of rock in the sea near a coast
arch
Third
When the cave erodes all the way through the head land, an arch will be created
An arch is a vertical curved structure that spans an elevated space and may or may not support the weight above it, or in case of a horizontal arch like an arch dam, the hydrostatic pressure against it.
stump
As the stack erodes at the bottom, it becomes very wobbly and in the end it collapses leaving a stump
When the arch has collapsed, a stack is left
