A ridge of sand that runs parallel to the shore is called a sandbar. Sandbars are typically submerged or partially exposed at high tide and can be an important habitat for marine life.
Longshore currents move sand along the coast by carrying it parallel to the shoreline. As waves approach the shore at an angle, they generate a current that moves sediments in a zigzag pattern. This process helps to redistribute sand along the coastline.
Transverse dunes are long sand ridges that are oriented at right angles to the prevailing wind direction. They form when wind blows sand over a stationary object, like a plant or rock, causing the sand to accumulate into a ridge perpendicular to the wind direction.
Spits, tombolos, barrier islands, and beach berms are coastal features created by wave deposition. Spits are elongated ridges of sand or shingle extending from the mainland into the sea, tombolos connect an island to the mainland, barrier islands are long, narrow offshore deposits of sand running parallel to the coast, and beach berms are elevated ridges of sand along the backshore of a beach.
A long-shore current can change a beach by transporting sand along the coastline. This can result in the erosion of some areas while causing deposition of sand in others. Over time, the beach's shape and size may be altered due to the long-shore current's influence.
Long sand ridges oriented nearly parallel to the prevailing wind are called sand dunes. They are formed by the deposition of sand carried by the wind and are common in deserts and coastal areas.
sand ridges that rise slightly above the surface of the sea and run roughly parallel to the shore, from which it is separated by a lagoon.
