youngest at deep-sea trenches
thinnest in subduction zones
oldest near ocean ridges
youngest near ocean ridges
10
Crust is neither destroyed nor formed along which of the following boundaries?
divergent
magnetic
transform
convergent
11
Which letter represents a convergent plate boundary?
Y
S
X
R
12
Lava that has low viscosity moves ______________ than lava with high viscosity.
Lower
Slower
Greater
Faster
13
The magnetic pattern of ocean-floor rocks on one side of an ocean ridge is
a mirror image of that of the other side
much different from the magnetic pattern found in rocks on land
younger than on the other side
at right angles to the ocean ridge
14
Which letter represents a divergent boundary?
X
S
Y
R
15
The hotter the magma or lava, the ______________ the viscosity is.
Lower
Greater
Faster
Slower
16
The driving forces of tectonic plates are related to convection currents in Earth’s
outer core
inner core
crust
mantle
17
Subduction results in the formation of
rift valley
magnetic reversal
new continental crust
deep-sea trench
18
What powers the rock cycle?
Heat and pressure
Pressure and wind
Location and pressure
Heat and location
19
Crust is neither destroyed nor formed along which of the following boundaries?
divergent
convergent
magnetic
transform
20
Each cycle of spreading and intrusion of magma during seafloor spreading results in
plates colliding
magnetic reversals
new ocean crust
subduction
21
What letter represents the subduction zone?
A
C
B
D
22
Which of the following is NOT a rock family?
Sedimentary
Molten
Igneous
Metamorphic
23
Continental drift was not widely accepted when it was first proposed because
mantle convection currents weren’t in motion at that time
continental landmasses were too big to move slowly over Earth’s surface
magnetic and sonar data proved that Wegener’s hypothesis was incorrect
Wegener couldn’t explain why or how the continents moved
24
What is erosion?
Dropping sediment carried by wind or water from one location to another
Process where rock is worn away by wind, water and ice
Process where rock is transformed into diamonds
Tiny pieces of rock

metamorphic
molten
igneous
sedimentary

older
younger
magnetically reversed
the same age
30
What is NOT a slow earth change?

Deposition
Erosion
Weathering
