Tombolo

• Explain long shore drift.
• Due to long shore drift material is constantly moved along the coast line.
• When coastline changes direction the longshore drift continues causing material to be deposited in a long thin strip not attached to the coast (spit).
• If this spit moves in the direction of an island and connects the island to the mainland, a tombolo is formed.
• Tombolo example: Chesil beach connecting to Isle of portland.
