Grade 5: SOL 5.7 Earth’s Changing Surface and the Rock Cycle hot liquid rock beneath the earth's surface magma lava hot liquid rock above the earth's surface igneous rock rock formed by the cooling and hardening of magma or lava rocks formed from sediments that have been pressed and cemented into rock Created by A. Wong, Sugarland ES sedimentary rock rock formed when sedimentary or igneous rocks are changed due to heat, pressure, or chemical reactions. metamorphic rock rock cycle continuous changing of rock from one type to another over time fossil imprint or shape of a plant or animal left behind in rock breaking down of rock into small pieces by wind or weather Created by A. Wong, Sugarland ES weathering mantle layer of the earth under the crust that has hot, molten rock layer of mud that settles over time on the bottom of a lake, river, ocean, stream or pond sediment two most common forces that cause rocks to break down into smaller pieces wind and rain wind and water these two forces cause lava to cool Created by A. Wong, Sugarland ES pressure to push or press down heat, pressure, weathering, and erosion processes that change rocks classification key a chart used to help identify different kinds of rocks fossil evidence provides information about life and changes in the Earth long ago Created by A.
