What was the main reason that Wegener's theory received a lot of ridicule from the scientific community?

• No similar fossils were found on different continents.

• There was no data to suggest any change in geologic structures.

• Wegener did not give a method on how the continents actually moved.

• The outlines of the continents looked like puzzle pieces that would fit together.

A teacher taps on a hardboiled egg until cracks appear on the surface. She gently presses the egg between her fingers and thumb. The students observe some changes in the eggshell, a few of which are presented in the table. What is the teacher trying to model?

• weathering of rocks

• retreating glaciers

• formation of volcanoes

• tectonic plate movements

How did the Appalachian Mountains form?

• Folded mountains occur when two plates of the Earth's crust

  separate.

• Folded mountains are the result of many volcanoes erupting all

  at the same time.

• Folded mountains form over millions of years as sediments are

  deposited and build up.

• Folded mountains occur when two plates of the Earth's crust

  push against each other.

How has the concept of plate tectonics influenced our understanding of Earth's history?

• By determining the age of the Earth's core

• By providing evidence for the existence of ancient civilizations

• By explaining the formation of fossil fuels

• By helping to reconstruct past continental configurations and climate changes

How are divergent and convergent boundaries different?

• Divergent boundaries involve plates sliding past each other, while convergent boundaries involve plates moving apart.

• Divergent boundaries involve plates moving apart, while convergent boundaries involve plates colliding or coming together.

• Both involve plates moving away from each other, but only divergent boundaries create new crust.

• Both involve plates colliding, but only convergent boundaries cause earthquakes.
