Final answer:
Tides influence the beach profile by redistributing sediment, altering water depth, and changing wave action.
Step-by-step explanation:
Tides influence the beach profile primarily by redistributing sediment, altering water depth, and changing wave action. When tides rise, they bring in sediment from the ocean and deposit it on the beach. As tides recede, they take sediment back to the ocean, resulting in a continuous cycle of sediment redistribution. Additionally, the rise and fall of tides cause changes in water depth, which can affect the shape and form of the beach. Finally, tides impact wave action, with higher tides often leading to more powerful waves that can shape the beach profile through erosion and deposition.
