sandspit

• 1. sandspits formed by process of longshore drift
• 2. swash, where waves, driven by prevailing wind push material up the beach at an angle
• 3. returning backwash, is dragged back by gravity down the beach at right angles
• 4. spits form when theres a change in wind direction on a coastline, allowing a sheltered area for deposition, material slowly builds up and appears above water
• 5. spit develops if the supply of deposits is greater than amount of erosion
• 6. shape can become hooked or curved at the end because of change in wind direction / currents
• 7. a saltmarsh may form in a sheltered area behind a spit eg. Spurn Head
