  1. What is a spit?
    Spits are long, nrrow beaches of sand and shingle that are attached to the land at one end. They extend across a bay, an esturary or where the coastline changes direction.
  2. How do spits form
    Longshore drift in one dominant direction. At a river estuary, the growth of a spit causees the river to drop its sediment. Occurs on landward side.
  3. What is a bar?
    When a spit joins two headlands. Any water on the landward side is trapped and forms lagoon.
  4. How is a bar formed?
    This formation is only possible if there is a gently sloping beach and no sizeable river is entering the bay.
  5. What is a tombolo?
    Spits that have continued to grow seawards until they reach and join an island.
  6. How are tombolos formed?
    Not only because of longshore drift, but also sediment being rolled towards the coast.
