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.
Erosion along a shoreline can be caused by wave action, currents, wind, and tides. These natural forces can slowly wear away the shoreline, leading to the removal of sediments and landforms over time. Human activities such as construction, dredging, and mining can also accelerate erosion along a shoreline.
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.
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.
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.

Erosion
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.
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.

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.
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.
This mechanism is involved in a number of processes: Hydraulic Action - where the waves ponding against the cliffs compress the air in cracks causing fracturing to occur. Corrasion (note carefully the spelling, this is different from corrosion) - which is a form of abrasion where small fragments of rock are hurled by the waves against the base of a cliff causing it to be worn down.

Waves break along the shoreline when they encounter shallow water, causing the bottom of the wave to slow down while the top continues moving forward, leading to the wave crest toppling over and breaking.
