Chapter 4 - Rocks: Mineral Mixtures. The Rock Cycle. Rock is: Naturally occurring Solid Mixture of one or more minerals Organic . Rocks are always changing. The process by which new rock forms from old rock material is called the rock cycle . http://youtu.be/pm6cCg_Do6kBy nassor

Rock Cycle. Earth’s inside. Crust. Thin outer layer 8- 40 km thick. Made of Solid rocks and minerals floating on liquid mantle. Mantle. A sea of molten rocks and minerals called Magma 2,900 km thick. Outer core. Ring of liquid iron 2,500km thick. Inner core.
Rock Cycle. Diagram of the Interior of the Earth. Crust 0 to 40 km 0°C. Upper Mantle 40 to 670 km 1,000°C. Lower Mantle 670 to 2,890 km 2,000°C. Outer Core 2,890 to 5,150 km 3,700°C. Inner Core 5,150 to 6,370 km 4,300°C.
Rock Cycle. It is the continual process of new rock being turned into old rock. Each type of rock can be changed into every other type of rock.
Rock Cycle. Rock Cycle. Rocks can be cycled and cycled. One rock can turn into another or form new rocks. Rock Cycle. Rock Cycle. The amount of matter remains constant while being recycled through the rock cycle . **Look at poster.
Rock Cycle. Igneous Rock. Formed when magma cools Inside the Earth Can be heated under pressure Becomes metamorphic rock Can be melted again to form new magma Above the ground Can be weathered and eroded Becomes sedimentary rock. Sedimentary Rock.
Rock Cycle. TAKS Objective 5 The student will demonstrate an understanding of earth and space systems. TEKS Objective: 8.12 The student knows that cycles exist in Earth systems. The student is expected to A analyze and predict the sequence of events in the lunar and rock cycles.
Rock Cycle. Shows the interrelationships among the three rock types Earth as a system: the rock cycle Magma Crystallization Igneous rock Weathering, transportation, and deposition. Rock Cycle. Earth as a system: the rock cycle Sediment Lithification Sedimentary rock
Rock Cycle. Sedimentary, Igneous, Metamorphic. What is a rock?. - A naturally formed solid that is usually made up of one or more types of minerals. - A few types of rocks are made of one mineral or no minerals. - ex: Limestone can be made entirely of calcite
Rock Cycle. Just a Review. 3 Types of Rocks Igneous Sedimentary Metamorphic. Igneous Rocks. Formed by magma from the mantle cooling and becoming solid. Cooling may happen on the surface of earth. Form at volcanoes, plate boundaries, etc… E xtrusive igneous rocks.
Rock Cycle. Sedimentary Processes. 1) Weathering & erosion. 2) Transport & 3) deposition. 4) Lithification.
