Right next to the coast
Ocean trenches
Subduction zones
2
Who is credited as first having the idea of continental drift?
Alfred Wegener

3
How does this picture of the location of earthquakes support the theory of plate tectonics?
It clearly identifies areas of seafloor spreading

Polylandmassia
Eurasia
Middle Earth
Pangaea
14
Evidence of seafloor spreading that compares lines of symmetrical rocks on both sides of mid-ocean ridges.
Nuclear Fusion
Subduction zones

Theory of Plate Tectonics
Convection Currents
16
Which of the following are evidences Wegener used to develop his idea of continental drift?
The location of earthquakes and volcanoes.
Evidence from seismic waves
Matching rock types on different continents
The continents fit together like puzzle pieces

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