The chemical composition of the magma and the rate at which it cools determine what rock forms as the minerals cool and crystallize. Figure 4. This flowing lava is molten rock that will harden into an igneous rock. Sedimentary Rocks WebJan 11, 2024 · Igneous rocks cool from magma. The appearance of the rock is created by the composition of the magma. It is also determined by the rate that the magma cools. If the magma cools deep underground, it cools slowly. If the magma cools at or very near the surface, it cools quickly. This results in two different rock types.
