One student made the incomplete diagram shown below to represent the relationship between magma, igneous rocks, and metamorphic rocks.

Individual labels for Magma, Igneous rocks, and Metamorphic rocks set up in a triangular shaped diagram.

Which of these is the correct next step to complete the diagram?

Put an arrow labeled heat and pressure, pointing from magma to igneous rocks.
Put an arrow labeled heat and melt, pointing from metamorphic 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 metamorphic rocks.

is it a pls help

To determine the correct next step to complete the diagram, we need to consider the processes involved in the formation of igneous rocks and metamorphic rocks.

- Igneous rocks are formed from the cooling and solidification of magma, which is molten rock beneath the Earth's surface. So, the correct next step is to put an arrow labeled "cools and crystallizes," pointing from magma to igneous rocks.

- Metamorphic rocks, on the other hand, are formed from existing rocks (such as igneous or sedimentary rocks) that have been subjected to heat and pressure. Therefore, the option suggesting an arrow labeled "heat and melt," pointing from metamorphic rocks to magma, is incorrect.

- The options mentioning "deposition and lithification" and "heat and pressure" are not relevant to the formation of igneous rocks from magma.

In summary, the correct next step to complete the diagram is to put an arrow labeled "cools and crystallizes," pointing from magma to igneous rocks.

The correct next step to complete the diagram is:

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

This arrow represents how magma, under the influence of heat and pressure, can solidify and form igneous rocks.
