a)
Ultima
b)
Pangaea
c)
Plate Tectonics
d)
Continental Drift
10.
If you traveled from the center of Earth to the surface, the pressure would...
a)
increase
b)
decrease
c)
stay the same
d)
unsure
11.
What evidence helped Wegener support his theory?
a)
Climate
b)
Fossils
c)
Mountains
d)
All of the Above
12.
Other scientists rejected Wegener's Continental Drift Theory because...
a)
He did not have evidence
b)
He couldn't explain how the continents moved
c)
He wasn't a scientist
d)
He was a bad communicator
13.
When the heat source is removed from a fluid, the convection current will
a)
stop immediately
b)
change directions
c)
eventually stop
d)
speed up
14.
Geologist believe the inner core is solid but hotter than the outer core which is liquid. What is their reasoning for this?
a)
This is not what they believe. Instead they think the inner core is liquid because with depth temperature increases causing the iron to melt.
b)
Because Earth is a sphere the interior takes on the same shape.
c)
Because all of the pressure from the overlying layers force the material to be a solid despite the hot temperatures.
d)
They have no evidence to support this claim, its just a guess.
15.
In the early 1900's Alfred Wegener found evidence of identical rock types, identical fossils, and matching mountain ranges on different continents that are on opposite sides of an ocean. What could be the explanation for these observations?
a)
All animals can swim extremely long distances
b)
These observations have no significant meaning.
c)
In the past, continents were not located where they are today but were joined together
d)
mountains are made through the same processes therefore they are very similar in their structure throughout the entire world.
16.
What does sea floor spreading do?
a)
Adds crust to the ocean floor
b)
Creates a canyon on the floor
c)
Subducts the floor
d)
Takes crust away
