i)A headland is attacked by wave erosion through abrasion and hydraulic action from both sides
-Caves develop on either side of the headland
-Continued erosion erodes thorugh the cave and eventually they join together to form a natural opening or tunnel through the headland known as an arch
ii) Sand and shingle is deposited from a headland seaward by a long shore drift
-Continued deposition leads to accumulation of sand towards an island forming a spit.With time, a bar of shingle/sand with one end attached to the mainland and the other to an island is formed.This bar is known as a Tombolo
