    • Bay
    • Cave
    • Arch
    • Stack

  8. Which rock type typically forms coastal headlands due to its high resistance?

    • Chalk
    • Sand
    • Clay
    • Alluvium

  9. A coast has soft clay at one point and harder rock at another. Which rock is most likely to form a bay?

    • Deposition
    • Hydraulic action

  18. What process forms distinct headlands and bays along a coast?

    • Differential erosion
    • Longshore drift
    • Mass movement
