Earth Science, Continental Drift & Earth's Interior, Review

Plate Tectonics is based on the Continental Drift Theory.

• YES!
• What? NO.
• I seriously don't know. 😭
• There is no record of that.

An enormous single large mass.

• Pannotia
• Pangaea
• Rodinia

What countries were once "together"?

• South America & Africa
• Africa & Australia
• Antartica & South America

Continental Drift Theory is still widely accepted today.

• YES!
• Noooooo?
• Maybe
• Plate tectonics is THE widely accepted.

Mesosaurus fossils are found between where?

• India
• Africa and South America
• Antartica
• Australia

What is this a picture of?

• plate tectonics
• continental drift
• pangea
• glacier scaring

What evidence did Wegener use in his theory?

• Continents and fossils fitting together/matching-up like puzzle pieces 
• glacier scars and evidence from temperature
• mountain ranges and coal deposits line up across continents
• all of the above

Why did no one believe Wegener's thoery?

• He could not explain HOW the continents moved
• He didn't have evidence
• His data was wrong
• He didn't use the right technology to gather data
