The Rock Cycle: Types of Rocks

The video tutorial explains the formation and characteristics of three major rock types: igneous, sedimentary, and metamorphic. It describes how igneous rocks form from cooled molten rock, either magma or lava, with examples like granite and basalt. Sedimentary rocks, such as sandstone and limestone, form from compacted sediments or organic remains. Metamorphic rocks result from the transformation of existing rocks under heat and pressure, with examples like slate and quartzite. The video provides a concise overview of these rock types and their formation processes.
