Which of these is the correct next step to complete the diagram?
Put an arrow labeled heat and melt, pointing from igneous rocks to magma.
Put an arrow labeled heat and pressure, pointing from magma to igneous rocks.
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.
