How are waves formed?

When you go to the beach, don’t you love to watch the waves crashing on to the shore? Do you know how these waves are formed? When the wind blows across the surface of the ocean, it pulls the water upwards. Gravity will pull it down again, creating ripples. If the wind is strong enough, and blows far enough over the water, these ripples build into waves. On calm days, waves are small. Waves grow bigger as the wind grows stronger. As they travel great distances, waves become more and more powerful.
