Metamorphic Rocks Characteristics and Types

This video tutorial introduces metamorphic rocks, explaining their formation through the metamorphosis of existing rocks due to intense heat and pressure. It covers the two types of metamorphism: contact and regional. The video classifies metamorphic rocks into foliated and non-foliated types, providing examples such as marble, slate, and quartzite. The tutorial concludes with a call to action for viewers to like and subscribe.
