|
Rock
|
A solid mixture of crystals of one or more minerals or other materials.
|
|
|
Composition
|
The makeup of a rock; describes either the minerals or elements present in it.
|
|
|
Texture
|
The sizes, shapes and positions of the grains that a rock is made of.
|
|
|
Rock Cycle
|
The process by which one rock type changes into another rock type.
|
|
|
Sedimentary Rock
|
Rock that forms when sediments are compacted and cemented together.
|
|
|
Strata
|
Layers of sedimentary rock that form from the deposition of sediment.
|
|
|
Metamorphic Rock
|
Rock that forms when the texture and composition of preexisting rock changes due to heat or pressure.
|
|
|
Magma
|
The hot liquid that forms when rock partially or completely melts; may include mineral crystals
|
|
|
Igneous Rock
|
Rock that forms from the cooling of magma.
|
|
|
Intrusive Rock
|
The type of igneous rock that forms when magma cools and solidifies beneath Earth's surface
|
|
|
Extrusive Rock
|
The type of igneous rock that forms when lava or pyroclastic material cools and solidifies on the Earth's surface
|
|
|
Lithification
|
The compaction & cementation of sediments forming sedimentary rocks
|
|
|
Metamorphic Rock
|
A type of rock that forms from an existing rock that is changed by heat, pressure, or chemical reactions.
|
|
|
Fusion
|
The change of a substance from a solid to a liquid state, usually by the application of heat
|
|
|
Frosion
|
Movement of material from one place to another on Earth's surface. Agents of movement include gravity, water, ice, and wind.
|
|
|
Crystallization
|
Process through which crystals separate from fluid, viscous, or dispersed state
|
|
|
Rock Cycle
|
Forces deep inside of the Earth and at the surface produce a slow cycle that builds, destroys and changes the rocks in the crust.
|
|
|
Mineral
|
A naturally occurring substance that is solid and stable at room temperature, represented by a chemical formula, usually not organic, and has an ordered atomic structure. It is different from a rock, which can be an made of many different minerals or non-minerals and does not have a specific chemical composition.
