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