Question

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

Put an arrow labeled heat and melt, pointing from sedimentary rocks to magma.

Put an arrow labeled deposition and lithification, pointing from igneous rocks to magma.

Put an arrow labeled cools and crystallizes, pointing from igneous rocks to sedimentary rocks.

Put an arrow labeled heat and pressure, pointing from sedimentary rocks to igneous rocks.

Answer 1

Answer is A

Step-by-step explanation:

I just took the quiz and got 100

Answer 2

The correct next step to complete the diagram is to put an arrow labeled heat and melt, pointing from sedimentary rocks to magma, because melting these kinds of rocks leads to magma.
B is incorrect because deposition and lithification create sedimentary rocks. C is incorrect because cooling rocks leads to igneous rocks, not magma. D is incorrect because heat and pressure create metamorphic rocks.
