Nettet29. okt. 2024 · Metamorphic rocks are rocks that have changed from one type of rock to another. While sedimentary rock is formed from sediments, and igneous rock is formed from molten magma, metamorphic rock is rock made from pre-existing rocks. These rocks undergo a change, either caused by high heat, high pressure, or exposure to … NettetDeep within the Earth it is so hot that some rocks slowly melt and become a thick flowing substance called magma. Since it is lighter than the solid rock around it, magma rises and collects in magma chambers. Eventually, some of the magma pushes through vents and fissures to the Earth's surface. Magma that has erupted is called lava.
Nettet6. mai 2024 · Igneous rocks form from cooling magma. Magma that erupts onto Earth’s surface is lava, as seen in figure 4. 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.
