Within the past decade, it seems as if we have seen more news stories about tsunamis than ever before. Within an overabundance of coastal cities, they have been able to leave a devastating mark of catastrophe and chaos – killing hundreds of thousands of people and destroying homes, villages and cities. Many people, though, are not sure about how tsunamis work and what causes them in the first place. Even though you might think the entire process is similar to a tornado or hurricane, this viral video from TED-Ed will break everything down for you beautifully. Before long, you will become a master of tsunamis and learn everything about how they work. However, you will also be forced to look at water, the formation of the Earth and the art of precipitation in a whole new light as well.
