Answer 1

Metamorphism

Question 2

Goal of Metamorphism -

Answer 2

reestablish equilibrium with new conditions.

Question 3

rocks that have been altered, changed or transformed in the solid state due to pressure, temperature conditions, and chemical reactions of hot fluids.

Answer 3

Metamorphic Rocks-

Question 4

were formed from organic mechanical or chemical sediments

Answer 4

Sedimentary rocks-

Question 5

where harden sediments become sedimentary rocks.

Answer 5

Lithification-

Question 6

formed from solidification of magma or lava

Answer 6

Igneous rocks-

Question 7

Formation of igneous rocks

Answer 7

intergrowth of crystals and/or volcanic glass
Crystalize is directly proportional to the cooling rate of magma
