Teaching Rocks – Igneous, Sedimentary, and Metamorphic “Today, we’ll be learning about three types of rocks,” Ms. Sneed tells her class. Cooling of magma leads to the formation of igneous rocks. Metamorphic rocks can also be formed from other metamorphic rocks. Rocks that form from magma at the surface are known as extrusive, or volcanic, igneous rocks. Most of Earth’s crust is made up of igneous rock. Igneous rocks are classified according to the relative abundances of different minerals. Basalt is an example of this type of rock. Find interesting information and a range of examples that help explain what igneous rocks are and what makes them different from other kinds of rocks. And if the solidification process takes place underneath the earth’s surface, intrusive or plutonic rocks are formed. Rocks and minerals are mined to help make things around us, from the large stone slabs used in buildings to the tiny pieces of metal in phones and jewellery.
