Types of Rocks and Their Formation

This video tutorial covers the classification and formation of rocks, focusing on igneous, sedimentary, and metamorphic rocks. It explains the processes involved in their formation, the characteristics of each type, and provides examples. The tutorial also highlights the importance of rocks in understanding Earth's geology.
