metamorphic and sedimentary rocks

All of the following conditions in Earth can cause metamorphic rocks to form EXCEPT ____. a. pressure b. exposure to air c. heat d. the presence of hot, watery fluids

b exposure to air

Sedimentary rocks form because of all of the following EXCEPT ____. a. crystals solidifying from magma b. sediments forming from solution c. sediments becoming pressed or cemented together d. water evaporating, leaving crystals behind

b sediments forming from solution

Metamorphic Rocks are rocks that have been changed by temperature and pressure. T or F

true

Metamorphic rocks can be formed from changes to an Igneous, Sedimentary, or other Metamorphic Rocks. true or false

true

Shale is an example of a clastic Sedimentary Rock

true

the process in which rock is exposed to air, water, or ice and breaks into pieces.

weathering

Foliated rocks are distinguished by ____. a. layers b. large mineral grains c. air holes d. lack of layers

a layers

Clastic rocks are ____. a. made from broken fragments of other rocks b. formed from magma c. deposited from solution d. all of the above

a made from broken fragments of other rocks. This answer is correct.

Sandstone is a(n) ____ sedimentary rock. a. chemical b. clastic c. organic d. none of the above

b clastic

a kind of clastic Sedimentary Rock

breccia

Conglomerate and ________ are made of the same material, but have different shaped grains. a. shale b. siltstone c. breccia d. sandstone

c breccia

Type of rock that contains evaporites like halite, calcite, and gypsum. a. organic b. clastic c. chemical d. all of the above

c chemical

_________ Sedimentary Rocks are classified by particle size. a. chemical b. organic c. clastic d. all of the above

c clastic

Metamorphic rocks that show layers of dark minerals alternating with layers of light minerals are classified as ____. a. nonfoliated b. intrusive c. foliated d. extrusive

c foliated

The process in which minerals hold sediment together, like glue, making a detrital sedimentary rock.

cementation

a kind of organic sedimentary rock

coal

The process in which pressure from the upper layers of sediment pushes down on the lower layers, causing the sediments to stick together and form solid rock.

compaction

a kind of chemical sedimentary rock

limestone

Sedimentary rocks are a. formed from magma b. formed because of changes in temperature and pressure, or the presence of hot watery fluids c. a type of foliated igneous rock d. formed when loose materials become pressed or cemented together or when minerals form from solutions

d formed when loose materials become pressed or cemented together or when minerals form from solutions

the movement of weathered material

erosion

Chemical Sedimentary Rocks are formed from the remains of once-living remains.

false

Nonfoliated rock will separate easily into layers. True False

false
