Deposition Is the process of dropping, or depositing sediment in a new location. Mineral- is a solid material with particles arranged in a crystal pattern Some uses for minerals are: jewelry, coins, metal objects, plaster, and electric wire. Mineral Properties 1.)Luster- describes how the mineral reflects light. (Shiny or dull) 2.) Hardness- is a mineral’s ability to resist being scratched. (Moh’s hardness scale) 3.) Streak- the color powder left behind when you rub the mineral against a white tile Rock- is a material made up of one or more minerals. Three types of Rocks 1.)Igneous 2.) Sedimentary 3.) Metamorphic Igneous rocks- forms when melted rock hardens Ex: Granite (kitchen counters), Pumice, and Obsidian. Sedimentary rocks- form when sediments are compressed and harden. Ex: conglomerate, limestone, sandstone Forces that can cause weathering water, wind, ice, and mass movement 5 agents of erosion 1.) Running water 4.) gravity 2.) Wind 5.) man 3.) glacier Examples of minerals: Diamond Talc topaz Metamorphic rocks- a type of rock formed by heat and pressure but not completely melted. Ex: schist, marble, quartzite Rock Cycle- the never ending process in which rocks are changed from one form to another. Processes involved in the Rock Cycle are: weathering, erosion, heat, pressure, melting, compaction, and cementation.
