Mineral Variety gold ore fluorite calcite magnetite Sedimentary rocks Erosion is the process of bits of rocks, sand, soil, and dead matter being moved by wind, water, and gravity. Eroded materials eventually settle on land or at the bottom of a body of water and become sediment. As layers of sediment pile up, the weight and pressure from the top layers cause the sediment on the bottom layers to harden, forming sedimentary rock. Igneous rocks Igneous rocks form from molten rock called magma found beneath the Earth’s surface. When magma reaches Earth’s surface and comes out during a volcanic eruption, magma is then called lava. Once on the Earth’s surface, lava will cool quickly forming igneous rocks. Magma may also cool and crystalize underground, near the Earth’s surface. Metamorphic rocks The weight of rocks pressing down on other rocks causes heat and pressure below the Earth’s surface forming metamorphic rocks. Metamorphic rocks can form from sedimentary, igneous, and other metamorphic rocks. Rocks are made up of many tiny pieces of minerals. Minerals are natural, nonliving crystals that make up rocks. They come in many sizes, shapes, and colors which is how scientists tell them apart. Minerals can be identifi ed by their physical properties such as color, luster, hardness, and streak color. Luster refers to the way surface of mineral refl ects light. The hardness of a mineral refers to how easily it can be scratched. Streak color is a physical property of minerals, which refers to the color streak a mineral leaves when scratched against a surface. streak Diamonds are the hardest of all minerals. They are also very refl ective. Hematite has a red brown streak. hematite quartz halite The Rock Cycle The rock cycle is the recycling of old rocks into new rocks. It is an ongoing cycle. The rock cycle is caused by heat, pressure, chemical reactions, weathering, and erosion. During the rock cycle, all three type(s) of rocks can change from one type of rock into another. It can take millions of years for rocks to move through this cycle.
