In 1912, Alfred Wegener proposed his Theory of Continental Drift. What was his theory?
All of the continents:
1) Used to be connected together as one supercontinent and then
2) Broke apart and moved (or drifted) to their current locations over time

Fit of the Continents:
Name a pair of continents that look like they fit together like a puzzle.
1) South America and Africa
2) North America and Europe (and/or northern Africa)
3) A combination of Africa, Antarctica, India, Australia
4) Etc...

A) Fern plant

Earth's interior is separated into layers because of differences in ____________.
Density
200
Put the layers of earth in order from most dense to least dense. Use all seven terms:
Asthenosphere, Outer core, Continental crust, Upper mantle, Inner core, Lower mantle, Oceanic crust
What were the five pieces of evidence that Wegener used to help support his Theory of Continental Drift?
The Fit of the Continents
Fossils
Glaciers (climate)
Coal Beds (climate)
Rock Layers

Glacial Evidence:
How does glacial evidence suggest that the continents have MOVED?
Glaciers form in cold areas and some glacial evidence can now be found in hot areas like Africa and India - so perhaps the continents moved from one area to another.

Approximately how thick is the entire Mantle?
About 3000 km

Put the layers of earth in order from least amount of pressure to most amount of pressure. Use all six terms:
Asthenosphere, Outer core, Crust (continental and oceanic), Upper mantle, Inner core, Lower mantle
Why do seismic waves travel really well through solids and not at all through liquids?
The molecules in a solid are close together and bump into each other easily. The molecules in a liquid are farther apart, so it's less likely they will continue to bump into one another.

TOTALLY RANDOM QUESTION THAT HAS NOTHING TO DO WITH THE QUIZ ALERT!!!
Of the following four singers/groups, which one does Mr. Rollins secretly like the best:
A) Justin Bieber
B) One Direction
C) Taylor Swift
D) Miley Cyrus
C) Taylor Swift

Coal Bed evidence:
How does evidence from coal beds support the idea that the continents were once all connected?
When you put the continents back together, the evidence from coal beds lines up nicely, especially in the northern continents (North America, Europe, Asia)
