Deposition by Waves
When waves move toward the shore, they carry sediments. As these waves slow down, they lose energy and deposit the sediments they carry.
Larger particles, like sand, settle along the shore, where waves are strongest, while smaller ones, like silt and clay, settle in calmer waters farther away. This process, known as wave deposition, creates various coastal landforms.
One such landform is a beach, which forms when waves deposit sand along the shore. In summer, gentle waves bring sand onto the beach, widening it, while in winter, stronger waves carry sand offshore, making the beach narrower.
Another one is a spit, a long ridge of sand that extends into the water, sometimes curving inward where the water is calmer.
Similarly, sandbars are underwater ridges of sand formed by waves.
Next, there are long, narrow islands of sand that form just offshore, which are called barrier islands. In their natural state, these vegetated, sandy areas allow sand to shift and move freely, acting as the first line of defense against storms such as hurricanes.
