Earth CFA #2 Review

Who was the German meteorologist that proposed the idea of continental drift?

• Hess

• Wegener

• Hubble

• Gruber

How did the fit of continents support Wegener's idea?

• Movement of ancient glaciers suggests coastlines have changed

• It looks like continents fit together like jigsaw puzzle

• Antarctica has evidence of a tropical climate

• Same species on distant continents, distribution unlikely unless plates move

What rock is found under the ice covering Antarctica?

• Granite

• Basalt

• Limestone

• Coal

What was the flaw in both Wegener's & Hess's hypotheses?

• They collected no evidence to support their ideas

• They kept their ideas secret

• They couldn't explain how or why movement occurred

• They didn't properly apply the scientific method
