There are very few things as peaceful as the sound of the ocean waves as they gently crest onto shore. It is a sound you can count on hearing every time you set foot in the beach.
But what causes this to happen? Waves are the result of energy moving through the water. And there are two main causes for the waves we find on the beach.
First as the wind moves over the surface of the water it creates friction, which cause surfaces waves. Second as the sun and moon move around the earth they exert a gravitational pull, which causes the tidal movement in the oceans and contributes the the waves that form in the water.
Fun Fact – The tallest wave ever measured was 1719 feet at Lituya Bay, Alaska.
