Igneous and Metamorphic Rocks: Contact Metamorphism

The video explains how cooking eggs is a chemical change, similar to contact metamorphism in rocks. When eggs are cooked, heat causes chemical changes, altering their color and texture. Similarly, contact metamorphism occurs when magma intrudes existing rock, causing it to become superheated and form new rock types.

How does the cooking of an egg relate to the process of metamorphism in rocks?

What is the significance of the portion of the egg closest to the heat during cooking?
