Rocks Rocking Our World: Types and Formation Explained

The video begins with a playful introduction linking rock music to the study of rocks. It then explains the three major types of rocks: igneous, sedimentary, and metamorphic. Igneous rocks form from cooled magma, with examples like pumice and granite. Sedimentary rocks are composed of compressed sediments, found in ocean and lake beds, with examples like sandstone and coal. Metamorphic rocks result from the transformation of igneous and sedimentary rocks under heat and pressure, with examples like slate and marble. The video concludes with trivia about the Earth's crust and the Taj Mahal.
