Answer 30

Cutting them up into little pieces to demonstrate the different minerals, mixing them up, and smushing them together with his hands.

Question 31

What is a metamorphic rock?

Answer 31

When sedimentary rocks go under heat and pressure, the minerals blend together, creating a new morphed physical change
