Rock
|
Mixture of minerals, mineraloids, glass, or organic matter
|
|
Rock Cycle
|
Model that shows how rocks are constantly changed from one form to another
|
|
Igneous Rock
|
Rock formed by the cooling and hardening of molten material from a volcano or from deep inside the Earth
|
|
Lava
|
Magma that eventually reaches the Earth's surface and flows from volcanoes
|
|
Extrusxive Rocks
|
Igneous rocks that form when magma extudes onto the Earth's surface and cools as lave...have a fine grained texture.
|
|
Intrusive Rocks
|
Igneous rocks that form when magma cools below the Earth's surface...usually have large mineral grains
|
|
Basaltic
|
Dark colored igneous rocks that form from magma that's rich in iron and magnesium
|
|
Granitic
|
Light colored igneous rocks formed from magma rich in oxygen and silicon
|
|
Metamorphic Rock
|
Rocks that change due to temperature and pressure or that undergo changes in their composition
|
|
Foliated
|
Type of metamorphic rock that's created when mineral grains flatten and line up in parallel bands
|
|
Nonfoliated
|
Type of metamorphic rock created when mineral grains change, grow, and rearrange but don't form bands
|
|
Sedimentary Rock
|
Form when sediments become presseed or cemented together or when sediemtns precipitate out of a solution
|
|
Sediment
|
Loose materials such as rock fragments, mineral grains, and bits of plant and animal remains that have been moved by wind, water, ice or gravity
|
|
Compaction
|
Sedimentary rock forming process that occurs when layers of small sediments become compressed by the weight of the layers above them
|
|
Cementation
|
Sedimentary rock-forming process in which large sediments are glued together by minerals deposited between the sediments
|
|
Waste Coal
|
Large Piles of poor quality coal lying near abandoned coal mines...this can genrate acide runoff.
|
|
Cogeneration
|
Process by which a power plant uses both the electrical and themal energy produced by the plant
|
