ES 07.1 Plate Tectonics - Continental Drift

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 sharring 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

Which of the following is evidence that supports continental drift?

• the presence of penguins at both the equator and Antarctica
• fossils of the same plant have been found on several continents
• the presence of glacial features in Antarctica
• the presence of volcanic rock in Antarctica

Who first developed the Theory of Continental Drift?

• Alfred Einstein

• Carl Jung

• Thomas Edison

• Alfred Wegener

Why was the theory of continental drift initially rejected?

• It didn't explain how continents move

• It did not explain formation of islands

• It was based upon false statements

• There was no data to support the hypothesis

Which of the following is NOT evidence of continental drift?

• Continents fit together like puzzle pieces

• Volcanic activity

• Fossil evidence

• Mineral, rock, and glacial deposit evidence

Present day fossils of similar organisms are found on different continents. This supports the theory of continental drift how?

• The environment of these organisms was once connected when continents were joined

• The organisms were avian and could live in a wide range

• The organisms often migrated

• The organisms had a large population that was widespread

Which of the following is evidence that mountain ranges on different continents were once connected?

• They have the same climate

• They are inhabited by similar wildlife

• They are the same age

• They have no trees beyond a certain height

Some fossils found on Antarctica required a tropical climate to live. How does this support the theory of continental drift?

• The climate at the poles of the earth is cold, meaning that Antarctica used to be closer to the equator.

• The climate at the poles of the earth was once warm

• The equator used to be at the poles of the earth

• The earth's orientation was once such that the poles of the earth were closer to the sun

Why don't present day continents fit perfectly together?

• Weathering and erosion of coastlines

• They have been twisted by earthquakes

• Fossils

• Human actions have changed the shape of coastlines
