Explanation:

Sea waves are formed when the winds blowing over the ocean surface transfer their kinetic energy to the water due to friction between the two.
Sea waves are an agent of erosion as well as deposition. Sea beaches are landforms of deposition only.
Like any other wave action, it is only energy and not the particles that move during wave motion/propagation. Particles only travel in small circles as the wave passes.
Waves are actually the energy, not the water as such, which moves across the ocean surface. Water particles only travel in a small circle as a wave passes. Wind provides energy to the waves. Wind causes waves to travel in the ocean and the energy is released on shorelines. Waves travel because wind pushes the water body in its course while gravity pulls the crests of the waves downward. The falling water pushes the former troughs upward, and the wave moves to a new position.
