|
rock:
|
a consolidated mixture of minerals.
|
|
|
igneous rock:
|
a rock formed by the crystallization of molten magma.
|
|
|
Sedimentary rock:
|
rock formed from the weathered products of preexisting rocks that have been transported , deposited, compacted, and cemented.
|
|
|
Metamorphic rock:
|
rock formed by the alteration of preexisting rock deep within earth ( but still in the solid state ) and heat, pressure, and/or chemically active fluids.
|
|
|
Rock cycle:
|
a model that illustrates the origin of the three basic rock types ad he interrelatedness of Earth materials and processes.
|
|
|
Magma:
|
A body of molten rock found at depth, including any dissolved gases and crystals.
|
|
|
Lava:

Magma that reaches Earth's surface

|
|
Erosion:
|
The incorporation and transportation of material by a mobile agent, such as water, wind, or ice.
|
|
|
Deposition:
|
the process by which an agent of erosion loses energy and drops the sediment it is carrying; also the process by which water vapor is changed directly to a solid without passing through the liquid state
|
|
|
Compaction:
|
process y which sediments are squeezed together by the weight of overlaying materials driving out water.
|
|
|
Cementation:
|
Solidification of sediments by the deposition of dissolved minerals in the tiny spaces between the sedimentary particles.
|
|
|
Contact metamorphism:
|
changes in rock caused by the heat from a nearby magma body.
