The diagram illustrates the formation of rock. In total, there are four stages.
The process begins with rain falling on the mountainside. Rainwater touches the fissures and rocks, causing fragility on its inner side and ultimately leading to their fragmentation into small pieces. Then, these pieces are carried out by the river. During this journey, they are broken up and transformed into pebbles and grains of sand, before reaching the sea. These pebbles and grains of sand, after a while in the sea, form a layer on the seabed. Finally, the water and water chemicals – borne act together, and the process of cementation starts with the formation of sandstone or mudstone, which are visible during low tide.
Overall, the rock formation process is complex and involves several natural elements, such as rain, water and water chemical – borne. The process starts with rainfalls on the mountainside, the erosion of rocks and fissures, and finishes with either sandstone or mudstone formation.
