- 1Crystalthe repeating pattern of a mineral's particles forms a solid
- 2Inorganicmust be able to form from materials that were not a part of living things
- 3Streaka mineral is the color of its powder
- 4Lusterdescribe how light is reflect from mineral's surface
- 5Mohs hardness scalerank the hardness of minerals
- 6Cleavagea mineral that splits easily along the flat surfaces
- 7Fracturehow a mineral looks when it breaks apart in an irregular way
- 8Geoderounded, hallow rock that is often lined with mineral crystals
- 9Crystallizationthe process by which atoms are arranged to form a material that has a crystal structure
- 10Texturethe look and feel of a rock's surface
- 11Igneous Rockforms from the cooling of magma or lava
- 12Sedimentary rockforms when small particles of rocks or the remains of plants and animals are pressed and cemented togethor
- 13Metamorphic Rockforms when a rock is changed by heat and pressure or by chemical reaction
- 14Extrusive Rockigneous rocks formed from lava that erupted onto Earth's surface
- 15Intrusive Rockigneous rocks that formed when magma hardened beneath the surface of Earth
- 16Weathering and erosionweathering-the effects of freezing and thawing and other forces on rock
erosion- process by which running water, wind, or ice carry away bits of broken-up rock - 17Depositionthe process by which sediments settles out of the water or wind carrying it
- 18Compactionprocess that presses sediments together
- 19Cementationthe process by which dissolved minerals crystallize and glue particles of sediments together
- 20Clastic Rocka sedimentary rock formed when rock fragments are squeezed together
- 21Chemical rockforms when minerals dissolved in a water solution crystallize
- 22Foliatedmetamorphic rock that's thin and has flat layering found in it
- 23NonFoliatedmetamorphic rock that has no layers
- 24Rock Cyclea series of processes that occur on Earth's surface and in the crust and mantle that slowly change rocks from one kind to another
