What makes a mineral a mineral? | Naturally occuring, Inorganic, Definate Chemical Composition |
Crystallization | Process by which a mineral grows |
Diamond | Mineral with the hardness of 10 |
Fracture | Mineral breaks rough, uneven or bumpy |
Cleavage | Mineral breaks evenly in smooth flat surfaces |
Streak | Powder produced when a mineral is ground up |
Talc | The softest mineral with a hardness of 1 |
Quartz | The most abundant silicate mineral on the earth |
Silicates | Rock forming minerals containing silicon and oxygen |
Color | The least reliable of test used to identify minerals |
Luster | The way the surface of mineral reflects light |
Specific Gravity | The density of a mineral compared with the density of water |
Rocks | An aggregate (combination) of one or more minerals |
Three rock types based on how they are formed | Igneous, Sedimentary, Metamorphic |
Intrusive rock | Igneous rock with large coarse crystal grains |
Limestone | Formed organically from seashells |
Rocks containing fossils | Sedimentary Rock |
Metamorphic Rock | Rocks formed from existing rock through heat, pressure, and chemical reactions |
Igneous Rock | Rock formed when molten rock cools and hardens |
Rock Cycle | The continuous process in which rocks change from one type to another |
Extrusive Rocks | Rocks that form as magma cools quickly as it leaves volcanoes. |
Granite | One of the most common intrusive rocks - known for its hardness (tombstone anyone?) |
Shale | Most commone sedimentary rock and indicates places where ancient seas covered the land |
Melting | Process by which rock becomes magma |
Weathering and Erosion | Processes by which Clastic Rock forms |
Volcano or Rift | Geological phenomena most likely to produce igneous rocks |
Slate (blackboards used to be made of this) | Sedimentary shale can be heated and pressured and turn into this |
limestone | sedimentary rock composed largely of the minerals calcite. Usually composed of skeletal fragments of marine organisms |
marble | metamorphosed limestone |
gravity | What causes a nebula or cloud of dust and gas to form a baby star? |
three quarters (3/4) | About ______ of the world's volcanoes are around the Pacific Rim and it is called the Ring of Fire. |
magma chamber | A collection of or lake of melted rock under ground that is under a LOT of pressure |
radioactivity from inside the earth gives off immense amount of heat | Why is the earth's center soooooo HOT? |
lithification | What is the name for the process that forms a sedimentary rock? |
Glue-like | Minerals left over after water has evaporated from sediment layers acts like |
SPACE | An atom is made up mostly of |
1/2 mile | If the nucleus of an atom were the size of a large marble, approximately how far away is the nearest electron? |
melting and crystallization | What process/es occur/s when a metamorphic rock turns in to an igneous rock? |
cementation | What is the process called when water seeps between the holes in a sedimentary rock then evaporates leaving minerals between the grains. |
