Igneous and Metamorphic Rocks: Metamorphism

The video tutorial explains how clay can transform into a single piece when subjected to heat and pressure, similar to the metamorphic processes that occur deep within the Earth. It describes how existing rocks can change dramatically due to heat, pressure, and chemical reactions. The concept of metamorphism is introduced, highlighting the transformation of one type of rock into another. To illustrate the intensity of pressure within the Earth, an analogy of stacking books on a hand is used, helping viewers imagine the pressure created by layers of rock thousands of feet thick.
