Classify to organize objects or events into groups based on common characteristics.
Deposition the natural process of adding transported sediments to a landform.
Erosion the transport of fragments of rock by water, wind, ice, or gravity.
Extrusive igneous rock rock formed from the cooling of molten rock on Earth's surface.
Foliation the texture of a metamorphic rock in which mineral grains are aligned like the pages of a book.
Fossil the remains or traces of a once-living organism that is preserved in rock.
Igneous rock rock formed from the cooling of molten rock.
Intrusive igneous rock - rock formed from the cooling of molten rock below Earth's surface.
Lava molten rock that has erupted onto Earth's surface.
Lithification the compaction and cementing of sediment into rock.
Magma molten rock below Earth's surface.
Metamorphic rock rock that has been changed by heat and pressure.
Rock cycle a continuous series of events through which a rock is transformed from one type to another.
Sediment rock fragments that have been transported to a different location.
Sedimentary rock rock formed from sediments, organic remains, or chemical precipitates.
Clastic sedimentary rocks are composed of rock fragments cemented together.
Organic sedimentary rocks are composed of the remains of living organisms. Examples include fossil limestone and coal.
Chemical sedimentary rocks are formed from chemicals dissolved in water. Examples include rock salt and travertine (a type of limestone).
Soil the top layer of Earth's surface that supports plant growth.
Soil contains a mixture of rock fragments, clay, and organic material.
Strata layers of sedimentary rock that form from the deposition of sediments.
Stratum is the singular form of strata.
Texture the sizes, shapes, and positions of the grains in a rock.
Weathering the breakdown of rock due to rain, wind, ice, sunlight, and plants.
