Question

understanding the rock cycle use the diagram above to help you. 1. using only the diagram above, explain what process must metamorphic rocks undergo to become igneous rocks?

Explanation:

To become igneous rocks, metamorphic rocks first need to undergo melting (due to high temperature and pressure deep within the Earth) to form magma. Then, this magma must cool and solidify (either intrusively, slowly underground, or extrusively, quickly at the surface) to form igneous rocks. This is based on the rock cycle, where the transformation from metamorphic to igneous involves melting into magma and subsequent crystallization.

Answer:

Metamorphic rocks must first undergo melting (due to high - temperature and high - pressure conditions) to form magma. Then, this magma needs to cool and solidify (through processes like intrusive cooling underground or extrusive cooling at the Earth's surface) to become igneous rocks.
