How is algarve beach formed?

Algarve beaches are primarily formed through a combination of natural processes including erosion, sediment deposition, and geological activity. The region's cliffs are shaped by wave action, which erodes softer rock layers, creating distinctive coves and sandy beaches. Additionally, sediment from rivers and coastal currents contributes to the accumulation of sand, resulting in the picturesque beaches that characterize the Algarve coastline. These factors, combined with the area's unique geology, lead to the formation of its stunning beach landscapes.
