Question

Which phenomenon leads to the formation of metamorphic rocks?

A. cooling of magma
B. deposition of sediments
C. heat and pressure
D. melting of rocks
E. minerals dissolving in water

Answer 1

When the igneous rock is deep underground for many years, it will form into metamorphic rock under extreme pressure and temperature. It could also form into magma when it melts deep beneath the layers of earth or it could form sediments when subjected to weather erosion. The answer is letter C.

Answer 2

The correct answer is C) heat and pressure.

The phenomenon that leads to the formation of metamorphic rocks.

Chemical alteration by heat and pressure create metamorphic rocks. Rocks on planet Eart are deformed and warped due to the action of plate tectonics, stress, and compression over many years. These rocks are then compacted so they are denser than their original material and there are not as sensitive to erosion.
