The diagram illustrates the process of coastal erosion and how it results in the discovery of fossils.
According to the diagram, the coastal erosion happened because of high tides hitting a cliff. Before the occurrence of the high tides and the erosion itself, the cliff stood out at a greater distance and tides were low which means the waves barely touched the cliff. On the other hand, during high tides, the waves would hit the cliff wall. Gradually, the power of these waves become stronger, hitting the cliff harder. This results in damage for lower parts of the cliff and causes the cliff to pull back. The stones from the lower part of the cliff fall into the sea and expose an area in the cliff where the fossils are buried. At the same time, the upper part of the cliff has minimal support. This causes the cliff to fall down, causing coastal erosion and creates a danger zone.
Therefore, if an erosion did not happen, the fossils would still remain buried and will not be discovered.
