Question | Answer |
Crystal | the repeating pattern of a mineral's particles forms a solid |
Inorganic | must be able to form from materials that were not a part of living things |
Streak | a mineral is the color of its powder |
Luster | describe how light is reflect from mineral's surface |
Mohs hardness scale | rank the hardness of minerals |
Cleavage | a mineral that splits easily along the flat surfaces |
Fracture | how a mineral looks when it breaks apart in an irregular way |
Geode | rounded, hallow rock that is often lined with mineral crystals |
Crystallization | the process by which atoms are arranged to form a material that has a crystal structure |
Texture | the look and feel of a rock's surface |
Igneous Rock | forms from the cooling of magma or lava |
Sedimentary rock | forms when small particles of rocks or the remains of plants and animals are pressed and cemented togethor |
Metamorphic Rock | forms when a rock is changed by heat and pressure or by chemical reaction |
Extrusive Rock | igneous rocks formed from lava that erupted onto Earth's surface |
Intrusive Rock | igneous rocks that formed when magma hardened beneath the surface of Earth |
Weathering and erosion | weathering-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 |
Deposition | the process by which sediments settles out of the water or wind carrying it |
Compaction | process that presses sediments together |
Cementation | the process by which dissolved minerals crystallize and glue particles of sediments together |
Clastic Rock | a sedimentary rock formed when rock fragments are squeezed together |
Chemical rock | forms when minerals dissolved in a water solution crystallize |
Foliated | metamorphic rock that's thin and has flat layering found in it |
NonFoliated | metamorphic rock that has no layers |
Rock Cycle | a series of processes that occur on Earth's surface and in the crust and mantle that slowly change rocks from one kind to another |
