Definition and Characteristics of Sea Caves

Sea caves are coastal formations shaped by the relentless pounding of waves against rocky cliffs. Found all around the world, they vary in size, shape, and depth. One telltale sign of a sea cave is the presence of a tidal zone where the waves meet the cave walls.

Sea caves can be categorized based on their shape. Some resemble tunnels, while others resemble shafts. They can be narrow or wide, and some stretch for several hundred meters.

How Sea Caves are Formed

The formation of sea caves is a process known as erosion. The ceaseless motion of waves, tides, and currents transports sand, pebbles, and rocks that scrape against the cave walls, wearing them down over time. The water’s force carves intricate patterns and shapes on the walls, bestowing the caves with their unique character.

One standout example is the Benagil Cave, famous for its large ceiling opening that allows sunlight to filter in, creating an enchanted ambiance.
