11. which rock changes from one type to another
12. forms when pressure,temperature,or chemical processes change existing rock
14. metamorphic rocks that do not have mineral grains that are aligned in plane or bands
15. the size,shape,and position of the grains that make up a rock determine a rock's_

1. forms when magma or lava cools and hardens to become solid,it forms beneath or on earth's surface
2. when magma pushes into or intrudes surrounding rock below earth's surface and cools
