What is the Theory of Continental Drift?

• New continents are continually being created

  and destroyed.

• The layout of the continents is the same today

  as it has always been

• The continents have always been separate but

  may one day drift together to form a single

  continent

• All the continents were once one continent that

  broke up and drifted apart over hundreds of

  millions of years

Alfred Wegener proposed the Theory of Continental Drift. Which one of these does NOT support the theory Wegener proposed?

• Fossils that were similar were found on different continents.

• Bacteria was found all over the world.

• Shape of continents fit together to form a supercontinent called Pangea

• Climate seen as glacial or ice scarring are found all over the world.

Wegener's evidence supports his theory of a super continent that he named?

• Ultima
• Pangaea
• Plate Tectonics
• Continental Drift

Other scientists rejected Wegener's Continental Drift Theory because...

• He did not have evidence
• He couldn't explain how the continents moved
