Types of Rocks and Earth Structure

This video tutorial covers the study of rocks and minerals, including their types, formation, and uses. It explains the classification of rocks into igneous, sedimentary, and metamorphic categories, detailing their unique properties and formation processes. The rock cycle is described, illustrating how rocks transform from one type to another. The video also highlights the practical applications of rocks and minerals in construction, energy, and agriculture. A review section summarizes the key concepts, and a Q&A session addresses common questions about geology.
