Ielts Writting Task 1 The Diagram Below Illustrates How Fossil Were Exposed Beneath A Cliff As A Result Of Coastal Erosion

The diagram below illustrates how fossil were exposed beneath a cliff as a result of coastal erosionThe diagram represents an outcome of the influence of coastal erosion on a cliff, and how it leads to the exposure of fossils.Overall, as it can be seen from the picture, during with time the size of the rock gradually reduces due to the effect of waves and high and low tides.First of all, after having looked at the diagram, it should be acknowledged that high tides attack the bottom part of the cliff, and this is the main reason why the hollow part is often evident at the foot of the cliff. In addition to this, waves beat the cliff at half of its height and accelerate the erosion process. After a time, as the bottom part of the cliff slightly disappears, there is no support cliff`s upper part. Therefore, rocks from the top part fall down, creating a sloping rocky platform. The sea-front bottom cliff`s part is always being damaged by waves, which leads to the emergence of the danger zone. Under the pressure of the sea water the cliff`s surface retreats many times before the exploration of fossils
