1
One of Wegener's evidence for continental drift was
rock formations
the layers of the earth
the phases of the moon
alpacas
2
Mid-oceanic ridges are formed by
cooled magma that hardens between diverging plates
collisions of Earth's continental crust
bends and folds along subduction zones
the diving of oceanic plates
3
Heat escaping from the Earth's core create what in the mantle?
solidification of the mantle
air bubbles
convection current
new minerals
4
The theory that better explains why the continents move is the
theory of relativity
theory of plate tectonics
theory of continental drift
theory of evolution
5
Another evidence for Wegener's theory of continental drift is
the polar ice caps
ancient climate
kangaroos
the shape of Australia
6
The _ is that the Earth's lithosphere is divided into plates that move around on top of the _.
Theory of Continental Drift; mantle
Theory of convection currents; inner core
Theory of Plate Tectonics; asthenosphere
Theory of Earth's layers; outer core
7
Which layer of the Earth is liquid
outer core
crust
mantle
inner core
8
A convergent plate boundary occurs where two plates
move toward each other
move away from each other
move past each other
none of the above
9
A transverse fault boundary occurs where two plates
move over each other
move past each other
move away from each other
move toward each other
10
In the beginning, Wegener's theory was
rediculed by critics
easily accepted by critics
none of the answers provided
mostly accepted by critics
11
The ancient super continent that contained all the landmasses was called
Gondwanaland
Panthalassa
Pangaea
Laurasia
12
The scientist who first came up with the theory of continental drift was
Alfred Wegener
Neil DeGrasse Tyson
Bill Nye
Isaac Newton
13
How do scientists know about the structure of the Earth's interior?
drilling into the crust
the puzzle like fit of the coastlines
studying fossils on Earth's surface
studying seismic waves produced by earthquakes
14
The theory states that the continents were once joined together yet they began to move apart
the theory of evolution
the theory of relativity
the theory of pangaea
the theory of continental drift
15
All the continents were joined together in a super landmass called
pangaea
urkontinent
megacontinent
unity
16
A current proof we have for the theory of continental drift is
the Mesasaurus
the composition of Mars
the galapagos islands
plate tectonics
17
A zone where oceanic crust dives beneath continental crust is called a zone of
reduction
subduction
divergence
rifting
18
Wegener's theory was not accepted at first because
he had too much evidence
there were not that many scientist in geology
he could not explain how the continents moved
the people just did not care about continents moving
19
A divergent plate boundary occurs where two plates
move away from each other
move toward each other
move past each other
move over each other
