To recap, the lesson provides a diagram to explain how a tsunami forms. Rapid movement of the ocean floor displaces a column of water. A series of waves travel outward and fairly low heights of around three feet.
A tsunami (soo-NAH-mee) is one of the world’s most powerful and destructive natural forces. They can speed across the ocean as fast as a jet plane, swallow up islands and wipe out villages. But what causes tsuamis…?
Tsunamis begin in the middle of the ocean and gain tremendous size and power by the time they reach shore. Tsunamis can wipe out entire coastal villages or towns. Earthquakes, landslides, or volcanic eruptions can trigger waves in a nearby ocean. These waves may travel for thousands of miles.
9 lip 2014 · Alex Gendler’s TED-Ed Lesson “How tsunamis work” gives a thorough introduction to the towering terror of tsunamis, offering a comprehensive look at the history and science behind these swells. Here, we’ve broken down how these waves form in a series of animated GIFs.
