Pangaea was an ancient supercontinent made up of...

• America, Greenland, and Europe.
• Antarctica, India, and America.
• all of Earth’s continents.
• South Africa, India, Australia, and South America.

Evidence used by Wegener to supported his idea of continental drift included

• Ocean rocks and sediments
• Ocean floor topography
• Magnetic isochron patterns
• Climatic data

Peer scientists reviewing Wegener’s hypothesis of continental drift rejected his notion because

• His evidence was too few to make a valid conclusion 
• He did not explain how continents move and what moves them
• His evidence was not clear in showing  how continents were joined
• He lied by including false evidence

The rejection of Mr. Wegener's hypothesis  teaches us that

• Indirect evidence is not sufficient to prove a hypothesis
• Direct evidence is hard to find 
• Hypotheses are hard to prove
• Scientists of the early 1900s were not smart enough
