Which of the beach zones is this:

What are cusps?

• Series of small wavy ridges of sand formed by waves on a beach.

  Tend to occur on flatter areas within the foreshore.

• A ridge on the beach, formed by the deposition of material by wave action.

  Built up by the spring tide (largest tide).

• Semi-circular scalloped depressions cut into the lower edge of the beach.

  Not fully understood, but tend to occur along swash-aligned beaches.

• Ridges of sand produced by the circular action of waves when they reach shallow water.

  As friction slows the wave, it sweeps up sediment.

What are ripples?

• Series of small wavy ridges of sand formed by waves on a beach.

  Tend to occur on flatter areas within the foreshore.
