Praxis 5511 Practice Test Practice Question
In addition to heat, what else is generally needed in order for an extensive region of metamorphic rock to be formed?
Correct Answer: C
Rationale: Metamorphic rock formation requires both heat and pressure, making pressure essential for the process. Pressure facilitates the reorganization of minerals within the rock, leading to metamorphism.
Option A, erosion, is not directly involved in metamorphic rock formation; it primarily affects surface processes. Option B, water, can influence certain metamorphic processes (like hydrothermal metamorphism), but it is not universally necessary for all metamorphic rock formation. Option D, acid, may play a role in some chemical processes but is not a fundamental requirement for metamorphic rock development.
