the Rock Cycle Rocks amp the Rock Cycle Minerals and rocks are stable only under the conditions at which they form Change the conditions and the rocks will change to adapt to the new conditions. Hot rocks/Fire Rocks. Igneous Rock . Igneous rocks form . when molten rock cools and solidifies. . Molten rock is called magma when it is below the Earth’s surface and lava when it is above.. when molten rock cools and solidifies. “Liquid Hot Magma!”. Igneous Rocks. Rocks formed from cooling of lava or magma. Lava-Melted rock erupted from volcanoes and deposited on the earth’s surface. Cools quickly.. Magma-Melted rock that sits inside the earth in a magma chamber. Cools slowly.. Sedimentary rocks cover ~ 75% of Earth’s surface. ~ 5 % (by volume) of Earth’s outer 10 miles. Contain evidence of past environments:. Important resource. Coal, oil, and other fossil fuels. Groundwater resources. Mineral and Rock Vocabulary. Rock. Rock is a solid mixture of crystals of one or more minerals. Rocks are categorized into 3 types on how they are made. Each rock in each category is classified (named) by its TEXTURE and COMPOSITION. HIGHER-GRADE REGIONAL METAMORPHICS. Gneiss and Eclogite. 2. High-Grade Regional Metamorphic Facies. Rocks in this laboratory represent high to very high grade regional metamorphic rock. Facies represented are the amphibiolite, granulite, and eclogite facies. UNIT . 5. What are Sediments. Sediments are loose Earth materials (unconsolidated materials) such as sand . which are . transported by the action of water, wind, glacial ice and . gravity.. These . materials are . Sedimentary-sandstone. Metamorphic- gneiss. Igneous- diorite. 1. What is a Rock?. Naturally Occurring . (not man made). Solid. Mixture of minerals other organic matter. 2. What makes a rock different from a mineral?. Color . Texture. Light. Dark. Fine. Coarse . Igneous rocks are classified according to their. . origin. , . texture. , and . mineral composition. .. Origin . D. id it harden inside the earth or on the earth’s surface?. Rocks are classified by how they are formed, their composition, and texture. Rocks change over time through the rock cycle. TYPES OF ROCKS. ROCKS ARE DIVIDED INTO THREE GROUPS BASED ON HOW THE ROCKS . 2 – Soil. 3 – Landscape. Lithosphere. Lithosphere. The lithosphere is a rigid . part of the earth . that includes the earth's crust and part of the upper mantle . Ex. . Mountains, plains, volcanoes, etc.. 2 – Soil. 3 – Landscape. Lithosphere. Lithosphere. The lithosphere is a rigid . part of the earth . that includes the earth's crust and part of the upper mantle . Ex. . Mountains, plains, volcanoes, etc.. Sedimentary rocks form in 1 of 3 ways:. 1. . Clastic. Sedimentary Rocks- made of pieces and grains of other rocks. Material such as . sand . or . mud. -usually deposited in . water. Conglomerate sandstone. Which of following . is not. one of the three classes of rocks? . . Igneous. Metamorphic. Magma. What two processes change rock into sediments?. Cooling & Hardening. Heat & Pressure. Weathering & Erosion. January 2013. 3-1 What are rocks?. Rocks in Earth’s Crust. Petrologists. study rocks & minerals.. Rocks are made of minerals (2000). . Classification of Rocks. Classification is the grouping of things that are alike..
