First erosion, then forms a wave-cut notch, above is unstable rock. The material collapses and the material is cleared, then a new wave-cut notch is formed, the cliff retreats and then the wave-cut platform is created.

Where do headlands and bays form?

On alternating bands of resistant and less resistant rock along the coast.

How is a bar formed?

When a spit joins two headlands together.
