1
Moh's hardness scale is designed to test
the streak of a mineral
the hardness of a mineral
the color of a mineral
whether a mineral can be scratched or scratch another object
2
You would expect older crust to be near continents and newer crust to be
at transform boundaries
where tectonic plates diverge
where tectonic plates subduct
deep underground
3
Which tectonic plate is shown at #4?
South American Plate
Pacific Plate
African Plate
North American Plate
4
A mystery mineral can be scratched by a diamond, but not by corundum. The mineral is
Corundum
Diamond
Apatite
Topaz
5
The primary difference between intruisive igneous rocks and extruisive igneous rocks is that
there is no difference and are essentially both the same
magma forms extrusive rocks and magma forms instrusive rocks
extrusive has large crystal and intrusive has small crystal
lava forms extrusive rocks and magma forms intrusive rocks
6
A rock that undergoes melting, then hardening, then melting again will probably be
lava
metamorphic rock
magma
igneous rock
7
Volcanoes can typically form...
in the middle of a plate (ex. Hawaii)
along transform boundaries
along convergent boundaries
along divergent boundaries
8
What type of plate boundary is shown in the image?
divergent boundry
continental boundry
transform boundry
convergent boundry
9
The two metals that make up the Earth's core are
iron and dolomite
copper and tungsten
nickel and copper
nickel and iron
10
You would expect to find what type of rocks in and around a river?
sedimentary rock
magma
metamorphic rock
igneous rock
11
When two tectonic plates move away from each other it will create
a mountain range
a deep sea trench
a rift valley
new oceanic crust
12
Mountain building occurs where...
where two oceanic plates diverge
two oceanic plates converge
an oceanic and continental crust converge
two continental plates converge
13
Directly below the lithosphere you will find a semi-solid, flowing layer of the Earth called
the asthenosphere
the crust
the outer core
the lithosphere
14
Minerals are rubbed against an unglazed tile in order to determine its
hardness
streak
shinyness
luster
15
The tectonic plates are located within the Earth's
hydrosphere
closet
lithosphere
asthenosphere
16
Sediment can recombine through which process to make sedimentary rock?
compaction
weathering
cementation
erosion
17
As you travel through the Earth's layers you will eventually reach a...
liquid crust
solid inner core
liquid outer core
solid mantle
18
When two oceanic plates move towards each other, which one will sink below the other?
the less dense plate will push below the more dense plate
both plates will collide and make a mountain
the less dense plate will push above the more dense plate
no plate boundary like this exists so scientist don't know
19
An igneous rock that forms from magma is also called
extruisive
instruisive
nonfoliated
metamorphic
20
A mystery mineral can be scratched by calcite, but not apatite. Its hardness is probably
4 on the hardness scale
too difficult to determine
2 on the hardness scale
6 on the hardness scale
21
What is the main difference between foliated and nonfoliated metamorphic rocks?
nonfoliated rocks have mineral bands, foliated rocks do not
foliated rocks are always grey
nonfoliated rocks contain no minerals
foliated rocks have bands of minerals, non foliated do not
22
Which tectonic plate is shown at #2?
South American Plate
African Plate
North American Plate
Eurasian Plate
23
The Pacific plate has the honor of being the only major tectonic plate on Earth...
that is almost entirely made of oceanic crust
that has no volcanoes
that is broken.
that is not moving
24
Tremendous heat and pressure can form a/n
igneous rock
magma
sedimentary rock
metamorphic rock
25
The correct order for the layers of the Earth starting from the surface is
crust, mantle, outer core, inner core
inner core, outer core, mantle, crust
mantle, crust, inner core, outer core
crust, mantle, inner core, outer core
26
A mineral has a hardness of 7.8, which means
quartz cannot scratch it
a diamond would easily scratch it
feldspar cannot scratch it
it has a hardness close to topaz
27
What type of plate boundary will produce earthquakes and faults?
convergent boundary
oceanic boundary
divergent boundary
transform boundary
28
Why would you expect to find sedimentary rock around a river?
erosion and weathering are caused by the river
organisms around the river create sediment
during droughts the river creates new rocks
rivers provide compaction force to make these rocks
29
The only rock that can form from magma is called...
sedimentary rock
plymoth rock
metamorphic rock
igneous rock
30
When two plates move towards each other and one plate gets pushed below the other...
you get a rift valley
you get a trench
you get a a subduction zone
you get an earthquake
