Rocks Unveiled: A Journey Through Igneous Sedimentary and Metamorphic Types

The video tutorial explains the three main types of rocks: igneous, sedimentary, and metamorphic. It describes how igneous rocks form from cooled lava, sedimentary rocks from layers of sediment, and metamorphic rocks from existing rocks under heat and pressure. Examples of each rock type are provided, such as pumice and granite for igneous, sandstone and coal for sedimentary, and marble and slate for metamorphic.
