Rock Cycle |
a model that describes the formation, breakdown, and reformation of a rock as a result of sedimentary, igneous, and metamorphic processes.
|
|
|
Sediment |
Material (such as gravel, sand, mud, and lime) that is transported and deposited by wind, water, ice, or gravity; material that is precipitated from solution; deposits of organic origin (such as coal and coral reefs).
|
|
|
Surface |
the outside part or uppermost layer of something (often used when describing its texture, form, or extent).
|
|
|
Subsurface |
the stratum or strata below the earth's surface. |
|
|
Deposition |
form in two very different environments. All igneous rocks start out as melted rock, (magma) and then crystallize, or freeze.
|
|
|
Weathering |
The processes by which rocks are chemically altered or physically broken into fragments as a result of exposure to atmospheric agents and the pressures and temperatures at or near Earth's surface, with little or no transportation of the loosened or altered materials. |
|
|
Erosion |
The processes that loosen sediment and move it from one place to another on Earth's surface. Agents of erosion include water, ice, wind, and gravity. |
|
|
Heat |
the quality of being hot; high temperature. |
|
|
Pressure |
The force per unit of area exerted upon something, such as on a surface. |
|
|
Composition |
the nature of something's ingredients or constituents; the way in which a whole or mixture is made up. |
|
|
Cementation |
The process by which clastic sediment is lithified by precipitation of mineral cement, such as calcite cement, among the grains of the sediment.
|
|
|
Igneous |
form in two very different environments. All igneous rocks start out as melted rock, (magma) and then crystallize, or freeze.
|
|
|
Metamorphic |
Alteration of the minerals and textures of a rock by changes in temperature and pressure, and/or by a gain or loss of chemical components. |
|
|
Sedimentary |
Sedimentary rocks are those rocks made up of pieces of other rocks.
