How are waves created?
Waves are generated by wind blowing across the ocean surface. Strong, long-lasting winds blowing over great distances create the biggest waves. When a wave nears land, its base catches on the seabed and slows, while the top part carries on, curls over, and crashes down as a breaker. Waves are also generated by other disturbances, such as earthquakes. Ocean currents, flowing like underwater winds, move water around the oceans in giant circulations. Some currents are warm while others are cold, and this has a great influence on our weather.
