Introduction to Metamorphic Rocks

Introduction to metamorphic rocks Metamorphic rocks come from existing rocks that are subjected to extreme heat and pressure Welcome to MooMooMath and Science and metamorphic rocks. Metamorphic rocks are created when extreme heat and pressure changes the original structure into a new type of rock sedimentary igneous and even metamorphic rocks can all become metamorphic rocks when exposed to heat and pressure. the original rock is referred to as the protolith but it's commonly referred to as the parent rock. Contact metamorphism occurs when existing rock comes into contact with extreme heat like magma inside the earth and becomes something new Regional metamorphism is caused by extreme pressure. The pressure presses and squeezes the rock and transforms it. Kinda like gravity acts on this balloon. This will occur at convergent plate boundaries. Existing rocks are transferred into new rocks at these boundaries. two major types of metamorphic rocks are foliated rocks which have a layered or banded appearance and non-foliated which do not have these bands or layers 0:00 Metamorphic Rocks 0:42 Contact metamorphism results from 1:30 Nonfoliated Rock vs Mineral    • How is a Rock different than a Mineral ?
