Answers
1
What is a metamorphic rock?
crystallization of hot melted rocks or minerals
pieces of other rocks that are cemented together
existing rock that's changed by extreme heat and pressure deep underground
magma
2
What part of the Rock Cycle is A?
igneous
magma
metamorphic
sedimentary
3
At what type of plate boundary does subduction occur?
Spreading
Divergent
Transform
Convergent
4
The color a mineral leaves when it is rubbed on a hard white surface.
Streak
Luster
Cleavage
5
A mineral is considered natural, inorganic, and has a crystalline structure.
False
True
6
Why does density matter in tectonic plate movement?
It doesn't matter, all density is the same.
When an oceanic and continental plate meet, the oceanic plate will subduct.
7
According to Moh's Scale of Hardness, what is the hardest Mineral?
Talc
Calicite
Quarts
Diamond
8
Convection currents drive tectonic plate movement
True
False
9
How many major tectonic plates are there?
7
32
9
5986487272662
10
True or False: Earthquakes form when the tectonic plates slide past one another.
True
False
11
Which of these is NOT a property used to identify a mineral?
temperature
hardness
color
streak
12
What do tectonic plates make up?
lithosphere
crust
outer core
asthenosphere
13
Divergent plate boundaries occur when two tectonic plates move away (divide) from each other
false
true
14
Sediment become Sedimentary Rock through:
melting & cooling
heat & pressue
compacting & cementing
wind & erosion
15
What are the 4 MAIN layers of the Earth...?
lava, fire, water, land,
inner core, outer core, mantle core
outer core, water, mantle, core
16
Tectonic plates collide with each other.
divergent boundary
convergent boundary
transform boundary
17
Tectonic plates float on which layer of the Earth
Lithosphere (Crust and Upper Mantle)
Inner Core
Asthenosphere (Middle Mantle)
Outer Core
18
______________ is a measure of how easily a mineral can be scratched.
Density
Cleavage
Luster
Hardness
19
Most tectonic plates have two kinds of crust, what are they?
inner crust & outer crust
crust & mantle
soft crust & hard crust
oceanic crust & continental crust
20
Which of the following is
NOT
a characteristic of a mineral
It has crystalline structure
It is formed in nature
It is a solid
It is a living material
21
Convergent Boundaries can make which geological event?
none of the above
earthquakes
volcanoes
mountains
22
Tectonic plates sliding past each other in a horizontal direction.
divergent boundary
transform boundary
convergent boundary
23
Sedimentary rock is
A rock formed by cooling magma.
A rock formed by layers of sediments, compacted and cemented
A rock that formed by heat and pressure
A rock that falls from the sky.
24
Subduction happens when one plate goes under the other.
False
True
25
Sedimentary rock becomes Metamorphic through
melting
extreme heat & pressure
compacting & cementing
wind & erosion
26
What rock forms when existing rock melts into magma or lava cools and hardens?
Metamorphic
Sedimentary
Coal
Igneous
27
Define: Rock Cycle
Only happens to igneous rocks
A process that quickly changes rocks from one kind to another
A process that slowly changes rocks from one kind to another
Happens to only chemical rocks
28
An unknown mineral has a mass of 96.5 grams and a volume of 5 cm3. What is the identity of the mineral?
Aluminum 2.70 g/cm3
Copper 8.96 g/cm3
Gold 19.3 g/cm3
29
Luster is the way a mineral reflects light; lusters include shiny, dull, sparkly, and metallic
False
True
30
The rock cycle only moves in one direction.
True
False
