Rocks Around Us: Exploring Types and Formation in the Earth

The video explores the fascinating world of rocks, explaining their formation and classification into three main types: sedimentary, metamorphic, and igneous. Sedimentary rocks form from particles called sediments, metamorphic rocks form under heat and pressure, and igneous rocks form from cooled molten rock. The rock cycle illustrates how these types transform into one another. The video emphasizes the importance of rocks in understanding Earth's processes and encourages viewers to explore the types of rocks they encounter.
