How does longshore drift create a spit
WebFigure 13.2. 1 Longshore currents are caused by waves approaching shore at a small angle, moving water parallel to the shore (Steven Earle, “Physical Geology”). Another important effect of waves reaching the shore at an angle is that when they wash up onto the beach, they do so at an angle, but when that same wave water washes back down the ... WebLongshore drift moves material in a zig-zag manner along the beach. On a shingle or pebble spit, the pebbles become smaller and more rounded towards the end of the spit due to attrition. They also become smaller as the longshore drift becomes weaker. The formation of a spit The formation of a spit

WebLongshore currents and littoral drift Longshore currents distribute sand along the coast; this movement is called "littoral drift." The longshore currents flow Currentparallel to the shoreline in the surf zone and are caused by the waves that strike the beach at an angle rather than head-on. Waves approaching shore at an angle other than 90° bend WebBlakeney Point extends 6.4km (4 mi) and consists of sand, shingle and dunes. Material is moved along the spit carried by the action of the waves, through a process called longshore drift. On land, sediment is blown by the wind to form sand dunes. Sand and shingle accumulate and forms a narrow ridge where the direction of the coast changes.
