Rock Cycle

TermDefinition
Rock Cycle the series of processes in which a rock forms, changes from one type to another, is destroyed, and forms again by geological processes
Rock a naturally occurring solid mixture of one or more minerals or organic matter
Erosion the process by which wind, water, ice, or gravity transports soil and sediment forms again by geologist processes
Deposition the process in which material is laid down
Compostion the chemical makeup of a rock; describes either the minerals or other materials in the rock
Texture the quality of a rock that is based on the sizes, shapes, and positions of the rock's grains
Uplift the movement within the Earth that causes rock inside the Earth to be moved to the Earth's surface
Lava Flow when lava flows from a volcano or from fissures in the earth
Batholiths the largest of all igneous intrusions
Plutons large irregular-shaped intrusive bodies
Dikes intrusive bodies that are exposed over smaller areas than batholiths
Sills sheetlike intrusions that cut across previous rock units
Intrusive Igneous Rock rock formed from the cooling and solidification of magma beneath the Earth's surface.
Extrusive Igneous Rock rock that forms as a result of volcanic activity at or near the Earth's surface
Mafic Rock Dark-colored rocks; rich in calcium, iron, and magnesium, and poor in silicon
Magma liquid rock
Strata layers of rock (singular, stratum)
Fossiliferous Limestone cemented together animal remains
Stratification the process in which sedimentary rocks are arranged in layers
Organic Sedimentary Rocks forms from once- living plants or animals
Mud Cracks indicate the location of an old lake, stream, or shoreline; formed when fine-grained sediments at the bottom of a shallow body of water are exposed to air and dry out
Ripple Marks marks left from oceans, rivers, lakes, and sand dunes
index minerals rocks that only form at certain temps and pressures and are used to estimate the temp, depth, and pressure at which a rock undergoes metamorphism
recrystallization when the crystals of a mineral change in composition
folitated the texture of a metamorphic rock in which the mineral grains are arranged in planes or bands
nonfolitated the texture of metamorphic rock in which the mineral grains are not arranged in planes or bands
metamorphism when a rock goes through a process of change
contact meta occurs near igneous intrusions
regional meta when pressure builds up in rock that is buried deep below other rock formations or when large pieces of Earth's crust collide with each other.
deformation a change in the shape of a rock caused by a force placed on it
