This video discusses the formation of metamorphic rocks, one of the three major groups of rocks on Earth and the bedrock under much of North America. We explain that toast is a metamorphic form of bread and describe the conditions necessary for metamorphism to occur (burial of rocks, proximity to magma, plate tectonic settings). You will learn about the metamorphic temperature window, how developing a foliation is similar to squeezing a marshmallow, the names of some common metamorphic rocks, and what happen. Overview of metamorphic rocks and their formation. Including explanation of contact and regional metamorphism and the conditions in which they commonly form. Overview of a few examples of metamorphic rocks.
