CONTINENTAL DRIFT QUIZ

What does the Greek word ‘Pangaea’ mean?

• All Earth

• Connected Islands

• Large Continent

• Unified land

Who is credited for the theory of Continental Drift?

• 
• 
• 
• 

Which of the following statement BEST defines Continental Drift Theory?

• The continents were formed by convergent boundaries.

• The location of the continents at present time is the same with its locations 200 million years ago.

• The continents were once part of a single landmass that broke apart and have moved to their present locations.

• The continents are floating in a plastic like layer called asthenosphere and move by convection currents in the mantle.

What are the evidences gathered by Alfred Wegener to support his Continental Drift Theory?

• maps of all the continents

• remains of dead plants and animals

• the ancient climate of Antarctica and Africa 

• continental fit, rocks, fossils, coal deposits, ancient climate, and glaciers scars

Scientists discovered that there are large coal deposits in Antarctica. What does this indicate?

• It indicates that the polar regions have warmer climates.

• It indicates that the position of Antarctica never changed.

• It indicates that Antarctica was once dominated by plants and animals

• It indicates that Antarctica has plants adapted to very cold temperatures.

Which of the following was NOT used by Wegener as evidence of his theory?

• The apparent fit of the continents.

• reversals on the seafloor    

• Fossils that were found on different continents.

• Evidence of glacial scratches on continents found near the equator

How does the Mesosaurus fossil evidence support the theory of Wegener?

• Because it’s unlikely that the Mesosaurus existed on both continents

• Because it’s unlikely that the Mesosaurus could swim between continents.

• The Mesosaurus fossil evidence does not support his theory. It proves it wrong.

• Because the Mesosaurus lived millions of years ago, when scientists believe the continents began to move.

The theory of Wegener was not widely accepted when it was first proposed. What could be the reason?

• Continental landmasses were too big to move slowly over Earth’s surface.

• Magnetic and sonar data proved that Wegener’s hypothesis was incorrect.

• Wegener couldn’t explain why or how the continents moved.

• Mantle convection current weren’t in motion at that time.

Alfred Wegener was a meteorologist who studies weather, in his study, he figured out that the continents were like jigsaw puzzle. Which continent would best fit Africa to complete the whole puzzle?

• Australia

• Antartica

• India

• South America

IV.              Presence of Volcanoes and earthquake epicenters.

• I and II only

• I, II and III

• II, III and IV

• I,II, III and IV
