Unit 1 The Rock Cycle sediments- is naturally occurring material that is broken down by processes of weathering and erosion, and is subsequently transported by the action of fluids such as wind, water, or ice, and/or by the force of gravity acting on the particle itself Igneous- is one of the three main rock types, the others being sedimentary and metamorphic rock. Igneous rock is formed through the cooling and solidification of magma or lava. melting- solidification- weathering- is a process in which rocks are broken down by water, air, and living things.
Unit 2 Igneous Rocks pumice- a floating rock lava-is magma that reaches the surface magma-is molten material that forms deep beneath the Earth’s surface obsidian- granite- basalt- are made mostly of dark-colored silicate minerals and plagioclase feldspar. intrusive igneous rock-are formed when magma hardens beneath Earth’s surface. extrusive igneous rock-are formed when lava hardens.
Unit 3 Sedimentary Rocks deposition-occurs when an agent of erosion—water, wind, ice, or gravity—loses energy and drops sediments. compactiion-is a process that squeezes, or compacts, sediments. cementation-takes place when dissolved minerals are deposited in the tiny spaces among the sediments erosion- is the process by which material is removed from a region of the Earth surface sandstone- a common sedimentary rock consisting of sand, usually quartz, cemented together by various substances, as silica, calcium carbonate, iron oxide, or clay siltstone- a very fine- grained sandstone, mainly consolidated silt. shale- conglomerate- limestone- bituminous coal- clastic sedimentary rock- chemical sedimentary rock- form when dissolved substances precipitate, or separate, from water. evaporates-
