misc.
100
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
100
felsic
these types of igneous rocks are rich in elements such as aluminum, potassium, silicon, and sodium
100
strata
this term refers to layers of rock
100
contact metamorphism
this type of metamorphism occurs when rock is heated by nearby magma
100
foliated
the texture of meta. rock in which the mineral grains are arranged in planes of bands
200
erosion
the process by which wind, water, ice, or gravity transports soil and sediment from one location to another
200
mafic
rich in calcium, iron, and magnesium, and poor in silicon refers to what type of igneous rock
200
clastic
this type of sedimentary rock is made of fragments of rocks cemented together by a mineral such as calcite or quartz
200
regional metamorphism
when pressure builds up in rock that is buried deep below other rock formations or when large pieces of the earth's crust collide this occurs
200
deformation
this is a change in the shape of a rock caused by a force placed on it.
300
deposition
the process in which material is laid down
300
very slowly
igneous rocks that have large crystals and are coarse grained most likely cooled how
300
chemical
type of sedimentary rock formed from solutions of dissolved minerals and water
300
change
the term "meta" means what?
300
non-foliated
the texture of meta. rock in which the mineral grains are not arranged in planes or bands
400
composition
the chemical make up of a rock; describes either the minerals or other materials in a rock
400
magma
what do all igneous rocks begin as?
400
organic
formed from the remains of once living plants and animals are what type of sed. rock?
400
shape
the term "morphos" means what?
400
c. fossiliferous limestone
which of the following is an organic sed. rock? a. chemical limestone b. shale c. fossiliferous limestone d. conglomerate
500
texture
the quality of a rock that is based on the sizes, shapes, and positions of the rocks grains
500
extrusive
igneous rocks that formed as a result of volcanic activity at or near earth's surface are called what?
500
ripple marks
Sedimentary rocks sometimes record the motion of wind and water waves on lakes, oceans, rivers and sand dunes in features called what?
500
metamorphism
this occurs when temperature and pressure inside the earth's crust change
