A beach is a natural feature formed by the accumulation of sediment along the shore. The material is eroded by tides and waves, creating a concave shape that slopes down toward the body of water. Although some areas have rocky or sediment-rich shores, beaches are most commonly found along the coastline. The resulting deposits are called sand. Some beaches have no landforms, so the sand comes from sea sediment, while others are largely created by the action of waves or currents.
A beach is defined as an expanse of sand or pebbles along the shore. It may be located on a large river, a large lake, or an ocean. The composition of sand on a beach depends on the local bedrock and climate. Sometimes it is comprised of shells, seaweed, or marine organisms that have traveled long distances. The materials are also shaped by wind and waves. A beach may be a natural attraction in itself or serve as a recreation area for people.
The composition of a beach depends on the types of sediments found upstream of the beach. This sand is eroded by the movement of waves and wind. These materials may consist of rock fragments, sand, or mud. Most of the materials on a beach come from weathering. Waves and wind wear away land over centuries. Huge boulders are often beaten down to a few grains of sand.
The composition of a beach is affected by the sediments upstream. The state of compaction of the sediments determines how resistant it is to erosion. Compacted sediments will withstand higher levels of waves. Plant growth and established vegetation will slow the flow of fluid at the surface layer. The larger the amount of suspended particles, the greater the resistance to erosion. If the particles are not compacted, the erosional power of the moving fluid.
The composition of a beach depends on the types of sediments that are upstream of the shoreline. The composition of a beach varies from a sand beach to a pebbled beach. However, a beach may be formed near a large lake or ocean, as this will increase the volume of the water. If the sand is compacted, the beach will be more resistant to erosion. The presence of vegetation and trees will also reduce the impact of erosion.
The composition of a beach is determined by the types of sediments that surround it. For example, the sediments that make up a beach are moved by wind and water. The amount and size of these sediments affects the shape of the beach. A large beach has an inclination that is parallel to the shore. A sloping incline can cause the beach to become irregular. A rocky, pebbly sand beach may be flat.
