Answers
1
What movement occurs at a divergent boundary?
no movement at all
plates come together
plates slip past each other
plates move apart
2
T/F A fault is a line where the edges of Earth's plates meet.
True
False
3
The lithosphere is broken into separate sections called
faults
plates
continents
oceans
4
Which statement most accurately describes how the oceans have been affected by subduction?
Subduction results in the splitting of continents
Subduction results in the shrinking of ocean floor
Subduction causes the formation of new mantle
Subduction results in the rising of ocean floor
5
Collision of oceanic and continental plates result in
a deep ocean trench
a mid ocean ridge
a mountain range
a rift valley
6
If there are few deep-ocean trenches in an ocean then
the ocean will get larger
the ocean will get smaller
the continents will come together
nothing will change
7
T/F Sea floor spreading is the theory that all continents were once joined together.
True
False

conduction
17
What term is used to describe the ocean floor feature in which new oceanic crust is formed?
oceanic trench
continental shelf
mid-ocean ridge
seamount
18
The divergence of two oceanic crusts will form
a mountain range
a deep-ocean ridge
a rift valley
a mid-ocean ridge
19
