Q. How do waves form? _ Jessi McGovern.
A. The wind is responsible for most waves. When the wind is strong, the waves are higher. Earthquakes can also cause tidal waves. But scientists are studying a different type of wave that they call the giant wave. It is not a tidal wave, but it can be at least six stories high! A giant wave struck the Dwight D. Eisenhower in 1989. The wave came along suddenly off the coast of North Carolina and knocked three sailors off the ship, along with more than 35 missiles. Scientists believe these giant waves occur when two strong ocean currents collide _ or when a storm kicks up strong winds opposite the current.
