World Around Us - Natural Disasters

I hope that you enjoyed designing your earthquake safety poster last week. This week you are going to be learning about Tsunamis.


Lesson 18 – Tsunamis

In this lesson you will be learning about what a tsunami is and what causes them. A tsunami is a large ocean wave usually caused by an underwater earthquake or a volcanic explosion. Tsunamis are NOT tidal waves. Tidal waves are caused by the forces of the moon, sun, and planets upon the tides, as well as the wind as it moves over the water. With typical waves, water flows in circles, but with a tsunami, water flows straight. This is why tsunamis cause so much damage!
