Magnetic striping
Ocean trench
Subduction zones
Seafloor spreading
7
What does this picture represent?

12
What is the biggest reason Wegener's idea of continental drift was not accepted in his lifetime?
He was a meteorologist, not a geologist
He couldn't explain how the continents moved
It sounded too easy
People thought he looked like a crazy man

Continental Drift
Convection Currents
Theory of Plate Tectonics
17
This picture shows which of the following?
Seafloor spreading
Continental crust
Ocean trenches
Subduction zones
18
Area where old crust is destroyed.
Seafloor spreading

Middle Earth
Eurasia
Pangaea
20
Area where new crust is formed.
Magnetic striping
Ocean trench
Subduction zones

21
How does this picture of the location of earthquakes support the theory of plate tectonics?
It shows the ocean gets just as many earthquakes as land
It shows that earthquakes happen all over the world
The earthquakes outline the boundaries of tectonic plates
It clearly identifies areas of seafloor spreading
