The theory of seafloor spreading was proposed by.............
Harrison Hessenger
Harry Hess
Isaac Newton
Alfred Wegener
5
Greek word meaning "All Land"
Asthenosphere
Earth
Poptart
Pangea
6
How did Harry Hess use Sonar to develop the theory of SeaFloor Spreading?
He took a guess based off what he was hearing
He didn't, he used a different technology
He mapped the ocean floor and saw underwater mountain ranges (ridges)
Alfred Wegener told him about it

Crust
Lithosphere
Lower Mantle
Asthenosphere

False
13
What is an example may form when two continental plates CONVERGE?
Islands Rift Valley
San Andreas Fault
Carribean Islands

14
What observations lead Alfred Wegener to develop the theory of continental drift?
Same fossils/rocks/mountain ranges on diff coastlines
All of the above
"Maching" Shapes of coastlines
Evidence for climate change (tropical fossils in polar areas)
