What are they?

Rocks changed b/c of “intense heat & pressure”

Called metamorphism

Happens inside Earth’s crust

Bellwork

Molten (melted) rock can be found above and below Earth’s surface. What is it called in each of these places? How do the rocks that form above and below ground differ?

Use the textbook p. D40-D45 if necessary.
