WebExplain the 4 steps of how Spurn Head (spit) was developed. 1) Longshore drift moves material along the coastline. 2) A spit forms when the material is deposited. 3) Over time, the spit grows and develops a hook if wind direction changes further out. 4) Waves cannot get past a spit, which creates a sheltered area where silt is deposited and mud ... WebSpits are usually formed when re-entrance takes place by the longshore drift process from longshore currents. When waves at an oblique angle meet the beach, drift occurs. There is a deposit of sediment in a narrow strip in zigzag pattern moving down the beach.

Webspit, in geology, narrow coastal land formation that is tied to the coast at one end. Spits frequently form where the coast abruptly changes direction and often occur across the mouths of estuaries; they may develop from each headland at harbour mouths.
