Unit 2 Science

Front 1

Mineral

Back 1

Are inorganic, solid materials found in nature that always has the same chemical makeup.

Front 2

Rocks

Back 2

Is a solid inorganic material that is usually made of two or more minerals and can be metamorphic, sedimentary, or igneous.

Front 3

Crystal

Back 3

Solid material with atoms arranged in a repeating pattern.

Front 4

Gem

Back 4

Rare, valuable mineral that can be cut and polished.

Front 5

Ore

Back 5

Material that contains enough of a useful metal that it can be mined and sold at a profit.

Front 6

Igneous Rock

Back 6

Intrusive or extrusive rock that is produced when melted rock from inside Earth cools and hardens.

Front 7

Extrusive

Back 7

Describes igneous rocks that have small or no crystals and form when melted rock cools quickly on Earth's surface.

Front 8

Intrusive

Back 8

Describes a type of igneous rock that generally contains large crystals and forms when magma cools slowly beneath Earth's surface.

Front 9

Sedimentary Rock

Back 9

A type of rock made from pieces of other rocks, dissolved materials, or plant and animal matter that collect to form rock layers.

Front 10

Metamorphic Rock

Back 10

New rock that forms when existing rock is heating or squeezed.

Front 11

Foliated

Back 11

Describes metamorphic rocks with visible layers of minerals.

Front 12

Non-foliated

Back 12

Describes metamorphic rocks that lack distinct layers or band.

Front 13

Rock Cycle

Back 13

Diagram that shows the slow, continuous process of rocks changing from one type to another.
