Types of Rocks and Their Formation

The video introduces the three main types of rocks: sedimentary, ous, and metamorphic. Sedimentary rocks form from sediments under pressure, with examples like mudstone and limestone. Ous rocks originate from molten rock, either as lava (extrusive) or magma (intrusive), with examples like obsidian and granite. Metamorphic rocks form under heat and pressure, transforming existing rocks, with examples like marble and slate. The video concludes with a reminder to practice kindness.
