The diagrams below show how sedimentary rock is formed in coastal areas. Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

The presented illustrations depict the stages, involved in the formation of sedimentary coastlines.

, even though the diagram doesn't look extremely complicated, the whole process is very lengthy and multi-staged, with the unifying element throughout it being water. In the beginning, under the influence of rain, multiple cracks appear in the mountain. After some time, pieces of rocks are separated from the main body and, with the help of gravity, slide down to the nearest mountain river.

, the rocks are washed down the river to its bottom and begin to erode. In the next stage, transported downstream and settled in the sea, simultaneously being affected by exposure to water, the stones start decomposing and forming multiple layers of a potential coastline. The big stones form the lowest levels,
