Answers

1
Describe the motion occurring at the ridge formed at position 2
Pacific an Nazca Plates are both moving West
Pacific and Nazca plates are both moving East
Pacific is moving East and Nazca is moving West
Pacific is moving West and Nazca is moving East
2
The Appalachian mountains were once much taller than today. Why?
weathering and erosion
tectonic collisons
earthquakes
sedimentation and flooding
3
Describe a rift valley
two continental plates divide
two plates slide side by side
one oceanic plate moves under a continental plate
continental plates slides below an oceanic plate
4
When Australia moved northward after the breakup of Pangaea, what was more likely to survive?
organisms that migrated
organisms that required warm conditions
organisms that hibernated
organisms that lived in freshwater
5
An underwater volcano is also known as:
slope
fault
rift valley
mid ocean ridge
6
What best explains the break up of Pangaea?
plate tectonics
volcanic eruptions
greenhouse effect
coastal flooding
7
Which feature is formed by the separation of the North American and Eurasian tectonic plates?
mid ocean ridge
rift valley
ice cave
volcano
8
What land feature is most likely to form at the Nazca/ South American boundary?
Volcanoes
Rift Valleys
Mountains
Ridges
9
Describe the motion at the San Andreas Fault
Plates are moving in the same direction at varied speeds
Pacific plate is colliding with the NA plate
The NA plate is moving away from the Pacific Plate
Pacific and NA plates are moving in opposite directions
10
Which of these provides the best evidence for the theory of plate tectonics?
glaciers found at N and S Poles
puzzle like fit of continents
matching mountain rocks on opposites sides of the ocean
fossil clues on opposites side of oceans
11
Since Eurasia and North America are diverging, what change will this cause?
destruction of West European beaches
widening of the East African Rift Valley
formation of North American mountain
reduction of Pacific Ocean Size
12
Which of the following is the plate movement that forms the Himalayas?
2 continental plates converge
none of these, it's divergence
continental oceanic convergence
2 oceanic plates converge
13
Which of these best describes what is happening at the subducting plate?
more dense oceanic crust is destroyed as it slides down
Continent is being destroyed.
less dense ocean crust is being created.
Island is forming.
14
How can satellite imagery best be used after a hurricane?
check formation of deltas
check lake flooding
map topography of inland coasts
identify beach erosion
15
Which of Newton's Laws describe formation of the Himalayas?
Law of Inertia
none of these
3rd Law
2nd Law
16
What happens to ages of rocks as you move further away from the mid ocean ridge?
they get older
they get younger
ages alternate
All rocks are the same age
17
A volcanic Island Arc forms from what motion?
Diverging oceanic plates
Converging oceanic plates
Oceanic plates sliding side by side
Oceanic/Continental converging plates
18
Why did his peers not accept Wegener's theory of Continental Drift?
He couldn't explain how the plates move
He had no evidence to support his claim
He said the continents drifted on the oceans
Puzzle like fit was his only evidence
