What causes ocean waves to move ashore?

Ocean waves move ashore primarily due to the interaction of wind with the surface of the water, which generates energy that creates waves. As these waves travel across the ocean, they are influenced by factors such as the seafloor topography and ocean currents. When waves approach the shore, they encounter shallower water, causing their speed to decrease and their height to increase, eventually breaking and crashing onto the beach. This process is driven by the gravitational pull of the moon and the sun, which also affects tidal movements.
