The given process diagram demonstrates four layers of the evolution of the erosion of a headland.
Overall, erosion is a natural phenomenon that makes changes in the landscape. It destroys weak parts of rocks located near water objects like rivers or seas. At the first two stages erosion makes unsignificant damage which looked not critical. But the last two steps dramatically affect a headland.
The first picture shows that erosion begins in the middle of a mountain which is not strong enough to resist water pressure. The process starts with a little hole, but further it grows into a small cave. During years this cave becomes larger and may look like an arch. Such natural objects may have different names for example Durdle, Door or Dorset.
At the third stage of this natural process water totally destroys a cave, by beating it’s roof. And at the end of the erosion new parts of a landscape emerge namely headland retreating, stack and stump.
