The image shows four stages of the erosion of a headland. The first stage shows weak areas of rock being eroded. The second stage shows a cave becoming an arch, with an example given as Durdle Door, Dorset. The third stage depicts water beating against the roof stack. The fourth and final stage shows the headland retreating, leaving behind a stack and a stump. Each stage is represented by a diagram with arrows indicating the direction of erosion. No numerical data points, percentages, or trends are provided in the image.
Given the complexity of the image, the above description may not be entirely accurate.

The illustrations display the process of a headland’s transformation due to natural erosion. Overall, it can be seen that there are four main stages that lessen the size of the foreland through the erosion of the seawater.
At the beginning, waves repeatedly hit the cliff surface, causing the rock to erode at sea level. When it has been eroded for a long period, the rock penetrates into a wide area, causing a new geographical feature, which is an arch cave, also known as a Durdle Door.
Over time, the curve of the cave occupies more and more space, until finally, the ridge is torn apart, leaving the stump in the ocean. Following this, the remaining area of the headland and the stack are getting smaller by the force of sea waves.
