Types of Rocks and Their Formation

The video tutorial explores the three main types of rocks: igneous, sedimentary, and metamorphic. It explains how each type is formed through processes involving heat, pressure, and time. Key vocabulary terms are introduced, and examples of each rock type are provided. The lesson includes interactive activities to help students understand the concepts better.
