Question

One student made the incomplete diagram shown below to represent the relationship between magma igneous rocks and metamorphic rocks.
Which of these is the correct next step to complete the diagram?

A. Put an arrow labeled cools and crystallizes pointing from igneous rocks to metamorphic rocks

B. Put an arrow labeled cools and crystallizes pointing for metamorphic rocks to igneous rocks

C. Put an arrow labeled heat and pressure points in from igneous rocks to metamorphic rocks

D. Put an arrow labeled heat and pressure pointing from metamorphic rocks to igneous rocks

Answer 1

Answer:

C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks

Explanation:

Metamorphic rocks are changed rocks that are formed from pre-existing rocks that were once sedimentary or igneous rocks. Heat and pressure majorly act on igneous rock, which over time change these rocks into a different rock entirely, known as metamorphic rocks.

Therefore, the next step to complete the diagram will be:

"C. Put an arrow labeled heat and pressure pointing from igneous rocks to metamorphic rocks."
