Understanding Waves and Tsunamis

The video tutorial covers the concept of tsunamis, starting with an introduction to key vocabulary such as energy, particles, and waves. It explains how waves move and how energy is transferred through water particles. The tutorial then delves into the characteristics of tsunamis, their causes, and the impact of the 2004 Indian Ocean tsunami. Finally, it includes comprehension questions to reinforce learning.
