Transportation

• How is the material that has been eroded moved?

  It is moved around the coast by waves
• What is the process called that moves material along coasts?

  Transportation
• How is material transported along coasts?

  By a process called longshore drift
• What are the steps involved in longshore drift?

  1. Waves follow the direction of prevailing wind
  2. Waves hit the coast at an oblique angle
  3. Material is carried up the beach
  4. Material is then carried back down at right angles
  5. Over time, material zigzags along the coast
• What is the first step in longshore drift?

  Waves follow the direction of prevailing wind
• What happens when waves hit the coast at an oblique angle?

  They carry material up the beach
• What occurs after material is carried up the beach?

  It is carried back down at right angles
• How does material move along the coast over time?

  It zigzags along the coast
• What are the four other processes of transportation mentioned?

  1. Traction - large particles like boulders are pushed along
  2. Suspension - small particles like silt are carried in water
  3. Saltation - medium particles like sand are bounced along
  4. Solution - soluble materials are dissolved in water
• What is traction in the context of coastal transportation?

  Large particles are pushed along
• What does suspension refer to in coastal transportation?

  Small particles are carried in water
• How does saltation differ from suspension?

  Saltation involves bouncing medium particles
• What is solution in the context of coastal transportation?

  Soluble materials are dissolved in water
• What happens to material during backwash?

  It carries material down the beach
• How does direction of prevailing wind affect coastal processes?

  It influences wave direction and energy
• What is the relationship between wave direction and coastal erosion?

  Waves erode the coast based on their angle
• What is the effect of waves hitting the coast at an angle?

  They cause erosion and deposition
• How does the force of water affect sediment transport?

  It pushes sediment along the seabed
• What is the significance of understanding coastal transportation processes?

  It helps predict coastal changes and management
