QuestionAnswer
rock cycle series of processes in which rock forms, changes form one type to another, destroyed and forms again by geological process
rock naturally occurring solid mixture of one or more minerals or organic matter
erosion process by which wind, water,ice or gravity transports soil and sediment from one location to another
deposition process which matter is laid down
composition the chemical makeup of rock
texture quality of rock that is based on the sizes,shapes, and positions of the rock grains
uplift the rising of regions of the Earth's crust to higher elevations
intrusive igneous rock rock formed by cooling and solidification of magma beneath the Earth
extrusive igneous rock rock forms as a result of volcanic activity at or near Earth's surface
magma semi-hot liquid in the Earth's crust
sills sheet like intrusions that are oriented parallel to previous rock unit
plutons large irregular-shaped intrusive bodies
batholiths the largest of all igneous intrusions
mafic rock dark colored rocks that are rich in calcium,iron,and magnesium have very little silicon
dikes sheetlike that cut across previous rock units
lava flow when lava erupts from volcano
starta layers of rock
starttification process in which sedimentary rocks are arranged in layers
ripple marks wind and water waves on lakes, oceans, rivers and sand dunes
fossiliferous limestone cemented animal remains
organic sedimentary rocks either form when dissolved materials precipitate from solution or form from accumulation of plant or animal debris
mud cracks fine-grained sediments st the bottom od the shallow
foliated texture of metamorphic rocks in which mineral grains are arranged in planes or bands
nonfoliated texture of metamorphic rocks in which mineral grains are not arranged in planes or bands
regional metamorphism pressure builds up in rock that is buried deep below the other rock formations or when large pieces of the Earth's crust collide with each other
contact metamorphism heat of rock gradually decreases as the rock's distance form the magma increases and temperature decreases
metamorphism heated by nearby magma
index minerals only some minerals form at certain pressure and temperature
recrystallization during metamorphism mineral may change in size and composition
deformation change in shape of a rock caused by a forced placed on it
