Erosion is the main force that acts on rocks to break them down into sand. Water getting into cracks, freezing and expanding also helps to break down rocks.
The rocks are crushed into a pulp called liquefaction. They are broken down due to lightning hitting the rocks every century until finally the rock has become a fine powder. This is how rocks are broken down. Reference- William's Science Encyclopaedia
Cliffs retreat due to natural erosion processes such as weathering, gravity pulling rocks down, and the action of water and wind wearing away the cliff face. These erosion processes can cause the cliff to slowly retreat and change shape over time.
Rocks are naturally broken down into smaller pieces through a process called weathering. This includes physical weathering, where rocks are broken apart by factors like ice, wind, and water, as well as chemical weathering, where rocks are broken down by reactions with substances in the environment. Over time, these processes cause rocks to fracture and crumble into smaller particles.
Clastic sedimentary rocks.
All rocks can be broken down into smaller particles known as minerals. These minerals are the basic building blocks of rocks and can be classified based on their chemical composition and crystal structure.
Seddiment
A cliff retreat is a form of natural erosion. Rocks in the face of the cliff are broken down by wind and water (rain, waves, etc). The material in the cliff is loosened, and parts of the cliff face collapse. Eventually, an entire section of the cliff will fall into the sea, meaning that the cliff edge has retreated. The pace of cliff retreat is determined by the strength of the rocks in the cliff face, more than the cliff's height. It also most often occurs where the base of the cliff is continually being saturated by water, weakening the rock further.
