My topic is about tsunamis. Tsunamis are groups of waves that are maked by a movement under the water like an earthquake. Tsunamis have a big impact to the world. They kill people, destroy ships, kill fish, and destroy homes of poor people. Most tsunamis occur in the pacific ocean side and places where there are big bodies of water surrounding them. It's really sad for thwe people that live on those kinds of places because tsunamis hit them very often and tehy have to get used to it like the Florida people. Tsunamis occur in any season or temperature of the year. Temperature doesn't affect tsunamis, earthquakes under the sea floor only affect tsunamis. I've heard that people are building houses the are tsunami and tornado provedand that they are very expensive. I'm not sure of this, but it would help people a lot.
