Answer to Question 1

The wind blowing over the open ocean transfers some of its motion energy to the water because of friction between the moving air and the water surface. The energy in the water moves across the ocean as waves. When the wave reaches the shoreline, part of the energy is transfer to sound waves that we hear as the roar of the surf, as well as transfer of energy from the water to the seafloor to erode sediment.

Answer to Question 2

Both types of waves represent motion of energy through matter.
Both types of waves experience reflection and refraction.
The shape and motion behavior of ocean waves matches closely with vertically oscillating seismic surface waves, which are different from horizontally oscillating surface waves and body waves.
Seismic waves represent a short-lived pulse of energy moving through Earth and caused by release of elastic strain along a fault, whereas ocean waves represent continuous transfer of energy from wind to the water surface.
Ocean waves have wave heights in the range of 0.520 meters, whereas seismic surface waves rarely have wave heights greater than a few centimeters.
Ocean waves may travel as much as 1000 kilometers in a day, whereas seismic surface waves travel 1000 km in a few hours.
