Answers
1
Which type of crust is denser?
both
neither
continental
oceanic
2
Which type of plate boundary is pictured below?
divergent
convergent
transform
confounding
3
In which layer of the Earth are the convection currents responsible for plate tectonics?
lithosphere
mantle
outer core
inner core
4
This island arc would be found at what type of plate boundary?
Oceanic-Oceanic Convergent
Divergent
Oceanic-Continental Convergent
Continental-Continental Convergent
5
Which type of plate boundary created the Himalayas?
Ocean-Ocean convergent
Continental-Continental Convergent
Transform
Ocean-Continental Convergent
6
What geologic event occurs along the San Andreas fault?
earthquakes
subduction
tall mountains
trenches
7
What geologic event is occurring at the Mid-Ocean Ridge?
Volcanoes
New crust is formed
Tsunamis
Subduction
8
What evidence supported the Theory of Continental Drift?
Landform, Planetary, and Polar
Fossils, Landforms, and Climate
Continental, Transform, and Divergent
Climate, Weather, and Hydraulics
9
What type of surface feature would we find at this boundary?
tall mountains
island arcs
rift valleys
volcanoes
10
What force drags the tectonic plate along?
convection currents in the mantle
Island arcs
Subduction
Mid-ocean ridges
11
Why is Alfred Wegener important to geology?
He mapped the ocean floor using SONAR
He discovered sea-floor spreading
he came up with plate tectonics
He had the theory of continental drift
12
What surface feature is found at a divergent boundary?
subduction zones
rift valleys
tall mountains
trenches
13
Name the type of plate boundary shown in the picture.
Confounding
Divergent
Transform
Convergent
14
What geologic activity was discovered by Harry Hess along the Mid-Ocean Ridge?
SONAR
mountain building
volcanoes
sea-floor spreading
15
At what type of boundary would this new crust be formed?
transform
convergent
divergent
confounding
16
What happens when two oceanic plates converge?
They crash into each other and create mountains
They cause glaciers
Ocean plates only move away from each other
One plate is subducted under the other & crust is destroyed
17
What did Alfred Wegener call the "super continent" where all landmasses were joined together?
Pangaea
Super Max Plus
Asthenosphere
Megalithic
18
Which surface feature is found on the Earth at a transform boundary?
volcanoes
subduction zone
trenches
faults
19
Who was the scientist who discovered sea-floor spreading, the "how" of plate tectonics?
Alfred Hitchcock
Harry Hess
Alfred Wegener
Harry Styles
20
What type of plate boundary is shown below?
confounding
convergent
transform
divergent
