metamorphic
What is another word for FOLIATED for foliated rocks
layered
When sediment are depostied on the ground or sink to the bottom of a body of water this is called ________________
(In Lawyer terms, its when sworn evidence is given to get to "get to the bottom of the situation")
Deposition
This is molten rock ABOVE the surface of the earth
Lava
What kind of rocks can be used to make Metamorphic rocks?
A) Sedimentary B) Igneous
C) Metamorphic D) All of these
D) All of these
Why do intrusive rocks have larger mineral crystals formed than extrusive rocks?
Intrusive rocks cool off slower than extrusive rocks, giving the crystals more time to form larger crystals.
is a rock is the opposite of foliated, how do we describe it?
A) Infoliated B) Unfoliated
C) Non-Foliated D) Exfoliated
C) Non-foliated
This occurs when increased pressure forces grains of sediment together
(This is also how garbage trucks squish all the trash into neat little piles)
Compaction
This is molten rock BELOW the surface of the earth
Magma
The process of moving sediment from one place to another is called ______________
A) Weathering B) Deposition
C) Erosion D) Cementation
C) Erosion
Igneous rocks that are darker and more dense have these more of these minerals in them
iron and magnesium
What two factors are needed to create metamorphic rocks
Heat and Pressure
When water evaporates and minerals form between
sediment grains. The minerals act as a kind of glue
to keep sediments bound together
Cementation
When igneous rock cools just below the surface of the earth its called ________________
Intrusive
Marble for statues, Graphite for pencils, Crushed Gneiss for roads, blackboards are all made from these type of rocks
Metamorphic
Igneous rocks that are less dense and lighter in color, used to make glass, contains more of this mineral
Silica
What does the word METAMORPHIC also mean?
Meta means ____________
Morph(e) means ____________
Meta - Change
Morphe - form
The name of the physical and chemical process that slowly turns big pieces of rocks into much smaller pieces of rock is called ________________
A) Cementation B) Compaction
C) Weathering D) Deposition
C) Weathering
When igneous rock cools above the surface of the earth its called ________________
Extrusive
Rocks made from fragments of a variety of different rocks and minerals.
A) Organic Sedimentary
B) Clastic Sedimentary
C) Chemical Sedimentary
B) Clastic Sedimentary
Which type of crust contains more silica?
A) Continental
B) Oceanic
A) Continental
WHERE are metamorphic rocks formed?
A) Ocean floor B) Volcanoes
C) Deep within the earth
D) Just below the surface of the earth
C) Deep within the earth
Where do Sedimentary rocks form?
A) Deep within the earth
B) Low areas of earth's surface such as valleys and ocean basins
C) Volcanoes
B) Low areas of earth's surface such as valleys and ocean basins
What are the differences in minerals found in intrusive and extrusive rocks?
Intrusive rocks have larger minerals
Extrusive rocks have smaller minerals
Rocks that are made of materials left behind by once-living things.
A) Organic Sedimentary
B) Clastic Sedimentary
C) Chemical Sedimentary
A) Organic Sedimentary
How can you change one type of rock (Sedimentary, Igneous. metamorphic) to another? What is needed for each one to occur?
Heat: Igneous
Pressure: Sedimentary
Heat AND pressure together: Metamorphic
