In science we had to make a poster and we picked a card. I got a king which is Tsunamis. I like Tsunamis. I know a lot about them. Tsunamis are caused by an earthquake. It sends a big shake in the ground to a nearby ocean/lake. Then it is a big wave in the water and goes fast to the island, city, or town. Tsunamis can last up to a mile long. They can wipe out millions of people and homes. Tsunamis can be dangerous.
