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.

What does the theory of continental drift state?

• The continents were once joined in a super-continent and have moved over time
• Continents are stationary and do not move

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
