The Three Types of Rocks

The video explores the fascinating world of rocks, starting with igneous rocks formed from volcanic activity. It explains how these rocks can be extrusive or intrusive, with examples like pumice and granite. The video then transitions to sedimentary rocks, formed through erosion and weathering, highlighting types like sandstone and coal. Finally, it covers metamorphic rocks, transformed by heat and pressure, with examples such as marble and slate. The lesson concludes by encouraging further exploration of rock diversity.
