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

Well, deposition and oithfication is the process that creates sedimentary rocks, so the secon one is wrong.
When the magma cools and crystalizes we get an igneous rock, so 3 is wrong also.
Heat and pressure turns rocks into metamorphic rocks, so 4 is wrong also.
So it is the first one, wich is obviously true because magma is melted rock.
