Question

Which of these can be used to identify metamorphic rocks? Select all that apply.

color
texture
hardness
chemical composition

Answer 1

color texture and hardness

Answer 2

The correct answer would be texture and chemical composition.

Explanation:

The rock form by the transformation of pre-existing rocks by the process called metamorphism is called metamorphic rocks. The parent rock is subject to go through heat and pressure, leading profound chemical and physical change.

Metamorphic rocks can be identified and classified on the basis of texture (shape, grain size, and orientation) and mineral/chemical composition.

Thus, the correct answer would be texture and chemical composition.
