Exploring the Rock Cycle: Types and Formation

Mr. Bradley introduces the three main types of rocks: sedimentary, metamorphic, and igneous. Sedimentary rocks form from compressed layers of sediment, metamorphic rocks form under heat and pressure near magma, and igneous rocks form from cooled molten rock. The video includes demonstrations using starbursts and visits to geological sites like the Giants Causeway. The rock cycle is explained, showing how rocks transform over time. The video concludes with a summary and a teaser for a fossil hunting video.
