Exploring the Rock Cycle with Bill Nye

The video explores the fascinating world of rocks, starting with their historical significance and formation from molten lava. It delves into the rock cycle, explaining how rocks are broken down and reformed over billions of years. The video categorizes rocks into three main types: igneous, formed from cooled lava; sedimentary, created from compressed sediment; and metamorphic, transformed under heat and pressure. Each type is explained with examples, highlighting their unique characteristics and formation processes.
