Geology Concepts and Rock Types

The video explores the formation and types of rocks, starting from their cosmic origins. It explains how atoms and molecules form minerals, which crystallize to create igneous rocks. The process of weathering leads to sedimentary rocks, while plate tectonics transform rocks into metamorphic types. The video concludes by showing how geologists read rock layers to understand Earth's history.
