Most geologists rejected Wegener's idea of Continental Drift because _________.
He used too many pieces of evidence to support the idea.
He wanted to know what Earth looked like millions of years ago, which is impossible.
He couldn't identify what would cause continents to move around.
They were afraid of the new idea.
Wegener used the fit of the continents as evidence to support his hypothesis of Continental Drift.
true
false
Wegener used matching mountain ranges across different continents as evidence to support his hypothesis of Continental Drift.
true
false
Wegener used matching matching fossils of the same organisms on different continents as evidence to support his hypothesis of Continental Drift.
true
false
Wegener used evidence of glaciers in places now too warm as evidence to support his hypothesis of Continental Drift.
true
false
Wegener used the magnetic striping on the seafloor showing polar reversals as evidence to support his hypothesis of Continental Drift.
true
false
Wegener used matching rock types and ages across different continents as evidence to support his hypothesis of Continental Drift.
true
false
Wegener used evidence of convection currents in the mantle as evidence to support his hypothesis of Continental Drift.
true
false
What discovery revived Wegener's idea of Continental Drift and eventually led to the Theory of Plate Tectonics?
discovery of new fossils on Africa and South America
the discovery of mid-ocean ridges and seafloor spreading
the discovery of radioactive isotopes
none of the above
Who first proposed the idea of seafloor spreading?
Alfred Wegener
Harry Hess
James Hutton
Nicolaus Copernicus
Which of the following is evidence of seafloor spreading?
matching fossils on either side of the mid-ocean ridge
evidence of tropical plant fossils on the seafloor
same rock types in both North America and Africa
the magnetic striping on the seafloor on either side of the mid-ocean ridges
Why was the evidence of seafloor spreading so important to the idea of Continental Drift?
it answer the question for HOW continents could be moving
it disproved Alfred Wegener's hypothesis of Continental Drift
It shows how land bridges let prehistoric animals cross the oceans
all of these are true

What technological advances led to the acceptance of Wegener's Contienental Drift hypothesis?
sonar and magnetometers mapped the ocean floor
satellite communication allowed scientists to share ideas
computers were used to model tectonic patterns
fossils of the same organism were found on separate continents
Which of the following were peices of evidence used by Alfred Wegener to support his hypothesis of Continental Drift? (choose ALL that apply)
fit of the continents
