1.
The first installment to the Theory of Plate Tectonics was Alfred Wegener's Hypothsis of Continental Drift. What was the basic idea of the hypothesis?
a)
Modern continents are where they have always been.
b)
Modern continents are made up of many small land mass that have fused together.
c)
Modern continents were once part of a super-continent that broke part.
d)
Modern continents are slowly mnoving toward one another.
2.
Which of the following was not included in Wegener's supporting evidence?
a)
Animal fossils found on multiple continents.
b)
Plant fossils found on arctic islands
c)
New seafloor being made at the mid-ocean ridge
d)
Identical geological make-up on different continents
3.
What was the name Wegener gave to the supercontinents in his hypothesis?
a)
Terra Firma
b)
Pangaea
c)
Continent Maxima
d)
Gondwanaland
4.
What was the problem with Wegener's hypothesis?
a)
Not enough supporting data.
b)
Wegener wasn't a geologist.
c)
No mechanism describing how continents move.
d)
His data was flawed.
5.
In the 1940's, during World War II, Harry Hess began mapping the ocean floor, what was his first major discovery?
a)
Rift
b)
Deep-sea trenches
c)
Seamounts
d)
Mid-ocean ridge
6.
While investigating the mid-ocean ridge, what did Hess discover about the ocean floor?
a)
The ocean floor is flat.
b)
The age of the seafloor gets younger as you move further away from the mid-ocean ridge.
c)
Newest seafloor is found at the mid-ocean ridge and it gets older as your move away from the ridge.
d)
The age of the seafloor decreases as you get closer to a continent.
7.
The Theory of Seafloor Spreading states
a)
New seafloor is constantly being generated at the mid-ocean ridge, while older seafloor is recycled at deep-ocean trenches.
b)
New seafloor is constantly being generated at deep-ocean trenches and older seafloor is being
recycle at the mid-ocean ridge.
recycle at the mid-ocean ridge.
c)
The Modern continents were once part of a supercontinent called Pangaea
d)
The continents are being consumed at deep ocean trenches.
8.
How did the Theory of Seafloor Spreading help support Wegener's Hypothesis of Continental Drift?
a)
It didn't support Wegener's hypothesis.
b)
It provided the mechanism by which the continents move.
c)
It provided more evidence of clomate change.
d)
It provided more evidence for animal migration.
9.
In the Theory of Plate Tectonics, what is the mechanism that causes plate movement?
a)
Tidal forces in the oceans.
b)
Seismic waves in the lithosphere.
c)
Convection Currents in the asthenosphere.
d)
Magma waves in the asthenosphere
