Spit formation

• What is a spit in geographical terms?

  A depositional landform created by the sea
• How is a spit formed?

  Through deposition of sediment by water movement
• What is the prevailing wind direction in the UK?

  Southwest
• What is swash in coastal processes?

  The water moving at an angle up the beach
• What is backwash in coastal processes?

  The water returning straight down the beach
• What is longshore drift?

  The movement of sediment along the shore
• How does the prevailing wind affect longshore drift?

  It determines the direction of sediment movement
• What happens when sediment accumulates in a low-energy zone?

  It leads to the formation of a spit
• What is a characteristic feature of a spit?

  A curved end
• What is a salt marsh?

  A coastal ecosystem in intertidal zones
• What type of vegetation is commonly found in salt marshes?

  Reeds and grasses
• What is the significance of the recurved end of a spit?

  It is shaped by wind and wave action
• What is a bar in geographical terms?

  A spit that connects two land masses
• How does a bar differ from a spit?

  A bar connects land masses, a spit does not
• What does the term "intertidal zone" refer to?

  The area between high and low tide
• What processes are involved in the formation of both spits and bars?

  Longshore drift, swash, and backwash
• What is an example of a bar?

  Chesil Beach
• Why is a spit not large enough to reach the other side of a bay?

  It is limited by wave action and sediment supply
