Rocks And Minerals

Front 1

Rock

Back 1

Mixture of minerals, mineraloids, glass, or organic matter

Front 2

Rock Cycle

Back 2

Model that shows how rocks are constantly changed from one form to another

Front 3

Igneous Rock

Back 3

Rock formed by the cooling and hardening of molten material from a volcano or from deep inside the Earth

Front 4

Lava

Back 4

Magma that eventually reaches the Earth's surface and flows from volcanoes

Front 5

Extrusxive Rocks

Back 5

Igneous rocks that form when magma extudes onto the Earth's surface and cools as lave...have a fine grained texture.

Front 6

Intrusive Rocks

Back 6

Igneous rocks that form when magma cools below the Earth's surface...usually have large mineral grains

Front 7

Basaltic

Back 7

Dark colored igneous rocks that form from magma that's rich in iron and magnesium

Front 8

Granitic

Back 8

Light colored igneous rocks formed from magma rich in oxygen and silicon

Front 9

Metamorphic Rock

Back 9

Rocks that change due to temperature and pressure or that undergo changes in their composition

Front 10

Foliated

Back 10

Type of metamorphic rock that's created when mineral grains flatten and line up in parallel bands

Front 11

Nonfoliated

Back 11

Type of metamorphic rock created when mineral grains change, grow, and rearrange but don't form bands

Front 12

Sedimentary Rock

Back 12

Form when sediments become presseed or cemented together or when sediemtns precipitate out of a solution

Front 13

Sediment

Back 13

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

Front 14

Compaction

Back 14

Sedimentary rock forming process that occurs when layers of small sediments become compressed by the weight of the layers above them

Front 15

Cementation

Back 15

Sedimentary rock-forming process in which large sediments are glued together by minerals deposited between the sediments

Front 16

Waste Coal

Back 16

Large Piles of poor quality coal lying near abandoned coal mines...this can genrate acide runoff.

Front 17

Cogeneration

Back 17

Process by which a power plant uses both the electrical and themal energy produced by the plant
