The diagrams show how rock and stone fragments are dislodged from mountains and carried to the sea, eventually becoming sedimentary rock.

The process begins when rain falls on the mountainside, filling cracks and fissures with water. The water freezes and expands the cracks and fissures, breaking the rock around them. Dislodged rock and stone fragments then fall into the river below and are carried downstream. As this happens, the fragments are eroded by the river so that by the time they reach the sea, they have been reduced to pebbles and grains of sand. These sink in the sea, forming layers on the sea bed.

The rock-formation process then begins. Water and water-borne chemicals work between the pebbles and grains of sand, cementing them together over time. The result is a sedimentary rock of either sandstone or mudstone which can be seen when the tide goes out.

This process clearly shows how powerful water is and the role it plays in the formation of geological features over time.
