L4 : METAMORPHISM

Question 1

The process of _________ takes place tens of kilometers below the surface where temperatures and pressures are high enough to transform rock without melting it.

Answer 1

Metamorphism

Question 2

The Alteration of the composition or structure of a rock by heat, pressure, or other natural agents.

Answer 2

Metamorphism

Question 3

2 Factors that involved in the Process of Metamorphism.

Answer 3

Temperature and Pressure
