Question

1. which of the following does not describe contact metamorphism?

the heat may change the mineral composition of rock.
it involves small volumes of rocks.
it occurs during high levels of tectonic activity.
it occurs when magma encounters preexisting rocks.

Explanation:

Contact metamorphism is driven by heat from magma interacting with surrounding rock, altering mineral composition in small rock volumes. High tectonic activity is associated with regional metamorphism, not contact metamorphism.

Answer:

C. It occurs during high levels of tectonic activity.
