Question

Metamorphism is a physical and chemical change that occurs in such a way that?

1) disequilibrium is reached with the new physical and chemical environment
2) a dynamic equilibrium is reached
3) equilibrium with the new environment is disturbed
4) the rock reaches equilibrium with its new environment
5) the rock's chemistry and texture become increasingly unstable

Answer 1

Metamorphism is a process where the protolith reaches an equilibrium with its new environment, resulting in the formation of a metamorphic rock. The altered mineral content and texture of the rock represent adaptations to the changed conditions of temperature, pressure, or chemical interaction. option A is correct

Step-by-step explanation:

Metamorphism is a physical and chemical change that occurs to a pre-existing rock (the protolith) in such a way that the rock reaches equilibrium with its new environment. The process entails recrystallization of minerals due to changes in temperature, pressure, or interaction with chemically reactive fluids. This recrystallization does not melt the rock but changes

It's essential to remember that the specific characteristics of the resulting metamorphic rock, such as mineral content and texture, are determined by the original (parent) rock and the agents of metamorphic change like temperature, pressure, and chemically reactive fluids. option A is correct
