Wave action is a pounding force that causes erosion along the shoreline. Waves can carry sand and debris, which wear away the coastline over time. These actions, combined with tides and currents, can reshape beaches and cliffs.
Longshore drift is a type of erosion that moves sand along the shoreline. This process occurs when waves approach the shore at an angle, carrying and depositing sediment in a zigzag pattern along the coastline.
Most erosion along a shoreline typically occurs at point B, which is closer to the water's edge. Waves and currents tend to be stronger at this point, leading to more significant erosion compared to the area farther inland at point A.
A beach is formed by both erosion and deposition. Waves erode the coastline by picking up and moving sand and sediment, which then gets deposited along the shoreline to create a beach. Erosion and deposition processes continually shape beaches over time.
Weathering and erosion on the coast are primarily caused by the actions of wind, waves, and currents. These forces break down rocks and transport sediment along the shoreline, gradually shaping the landscape. Additionally, factors like tides, storms, and human activities can also contribute to coastal weathering and erosion.

An example of a shoreline deposition process is when sediments carried by rivers are deposited along the shoreline, forming beaches and sandbars. This process helps build up coastal features and contribute to shoreline stability.

Shoreline erosion is the process where waves, currents, and tides wear away or remove sediment and land along the shoreline. This can lead to the loss of beach areas, cliffs, and other coastal infrastructure. It is a natural process but can be accelerated by human activities like construction and climate change.
Waves breaking on a shoreline can cause erosion of the coast, reshaping of the beach, and the transportation of sand and sediments along the shore. They also help to oxygenate and mix the water in the coastal zone, benefiting marine life.
In Dubai, both weathering and erosion processes occur. Weathering can be observed in older buildings where the structures are worn down due to exposure to sunlight, wind, and sand over time. Erosion is commonly seen along the coastline where the action of waves and currents slowly shape the shoreline and sand dunes.

To help prevent erosion near a shoreline, you can plant native vegetation along the coast to stabilize the soil and absorb excess water. Building barriers like retaining walls or installing sand fences can also help reduce the impact of wave action on the coast. Avoiding construction near the shoreline and promoting sustainable coastal development practices can further prevent erosion.
Wave erosion is the primary type of erosion that causes beaches. Waves carry sand and other sediments away from the shore, shaping the coastline over time. Erosion by waves can create beaches through the deposition of sediment along the shore.
