Rock Cycle Vocabulary

Rock a mixture of one or more minerals, volcanic glass, organic matter, or other materials

a mixture of one or more minerals, volcanic glass, organic matter, or other materials

Sedimentary Rock forms when sediments are compacted and cemented together or when minerals are left behind by evaporation

forms when sediments are compacted and cemented together or when minerals are left behind by evaporation

Examples

Metamorphic Rock forms when heat and pressure act on igneous, metamorphic or sedimentary rock and change its form or make up .

forms when heat and pressure act on igneous, metamorphic or sedimentary rock and change its form or make up .

Examples

Igneous Rock intrusive or extrusive rock formed when hot magma cools and hardens

intrusive or extrusive rock formed when hot magma cools and hardens

Examples

Rock Cycle model that describes how rocks slowly change from one form to another through time

model that describes how rocks slowly change from one form to another through time

Example

Sediments loose materials such as rock fragments, dirt, silt, and sand

Magma hot, melted rock material beneath the Earth’s surface

Weathering surface process that breaks rocks into smaller pieces (wind, rain, temperature, etc)

Erosion process in which surface materials (sediments) are worn away and transported from one place to another by water, wind, and glaciers

process in which surface materials (sediments) are worn away and transported from one place to another by water, wind, and glaciers

Deposition The process of eroded materials being moved and deposited in another place.

The process of eroded materials being moved and deposited in another place.

Cementation sedimentary rock-forming process in which large sediments are held together by natural cements (matrix) like evaporated mud
