Final answer:
Wave energy, sediment size, and coastal vegetation are the factors that affect/influence the beach profile/form.
Step-by-step explanation:
Factors that affect/influence the beach profile/form include wave energy, sediment size, and coastal vegetation. Wave energy determines the force with which waves hit the beach, causing erosion or deposition of sediment. Sediment size affects how easily the waves can move and transport sediment, and coastal vegetation acts as a barrier, reducing the impact of waves on the beach.
