Rock
The series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geological processes.
Rock Cycle
The process by which wind, water, ice, or gravity transports soil and sediment from one location to another.
Erosion
The process in which material is laid down.
Deposition
The process in which water, wind, ice, and heat break down rock.
Weathering
Movement with in the Earth that causes rocks inside the Earth to be moved to the Earth’s surface.
Uplift
The chemical makeup of a rock; describes either the mineral or other materials in the rock.
Composition
The quality of a rock that is based on the sizes, shapes, and positions of the rock’s grains.
Texture
Grains of sediment that are compacted and cemented together.
Sedimentary Rock
At great depths, intense heat and pressure heat and squeeze the sedimentary rock.
Metamorphic Rock
The hot liquid that forms when rock partially or completely melts.
Magma
When magma cools and solidifies.
Igneous Rock
When uplift and erosion expose igneous rock which then weathers and wears away leaving grains of sand and clay.
