Wegner and Continental Drift

By Mollie Adams

Multiple Choice

Which of the following scientists put forth the Continental Drift Theory?

• Wegener

• Hess

• Einstein

• Churchill

Multiple Choice

Originally, the Continental Drift Theory was not well received by other scientists. Why?

• There was a competing theory at the time that was easier to believe.

• There was no data that showed the continents ever moved.

• The scientists didn't know the force responsible for moving the continents.

• The scientist presenting the data was unreliable.

Multiple Choice

These 3 animals above represent what type of evidence that the continents actually moved.

• Zoological evidence

• Glacial evidence

• Evidence of climate change

• Fossil evidence

Open Ended

Explain how this picture supports the Continental Drift Theory.

Open Ended

What was Pangaea?

Multiple Choice

Which of these terms means scratches in rocks caused by glaciers?

• Striations

• Stripes

• Stratosphere

• Stretch marks

Multiple Choice

What is the force that moves the continents?

• Conduction

• Convection

• Radiation

• Conveyor belts

Multiple Select

What was so strange about the ancient fossil records? (more than one answer)

• There were pieces missing.

• They were found across several continents that are now separated by oceans.

• The animals and plants, these fossils came from, could not have swam across the oceans.

• The animals and plants, these fossils came from COULD have swam across the oceans.

Multiple Choice

What do the geological records of the rocks show?

• Greenland and the Appalachian Mountains (U.S.) have the same rock structure and organization.

• China and Greenland have the same geological rock structure and organization

• None of the countries shared any similar traits

• All of the continents had the exact SAME composition and organization of rock.

Multiple Choice

What is the name for this ancient supercontinent?

• Pan Em

• Tethys

• Tetris

• Pangea

Multiple Choice

The super ocean surrounding Panges was called the _________ Oceans.

• Pan Em

• tetris

• Tethys

• Pangean

Multiple Choice

Why was Wegener's Continental Drift Theory laughed at by the scientific community at that time?

• He said the shifting of tectonic plates shifting along the mantle was responsible.

• His sonar machine was broke

• He looked too silly in that hat on the last slide.

• He proposed the continents plowed through the ocean

Multiple Choice

The idea that the North Pole Shifted due to continents moving is called

• Polar shift

• Apparent Polar Wander

• Continental Magnetism

• Wegener awesome hat!

Multiple Choice

Bathymetry means.....

• The measuring of how clean something is.

• The measuring of rocks

• The measuring of the depths of oceans and lakes

• The geological composition of the sea floor.

Multiple Choice

TRUE or FALSE: At times in the EARTH's history, the north pole was the south pole.

• TRUE

• FALSE

Multiple Choice

Where is the youngest ocean floor rocks found?

• Along ridge crests

• Farthest away from ridge crests

• in underwater seamounts

• in abyss's

Multiple Choice

What is the name of the scientist that formed a hypothesis that the continents were joined together as one landmass?

• Harry Hess

• Alfred Wegener

• Gregor Mendel

• Bill Nye

Multiple Choice

What is the name of the landmass that was created by the continents being joined together?

• Hawaii

• Euroasia

• Pangaea

• Antartica

Multiple Select

What evidence from landforms supports the idea that the continents were once joined and then drifted apart? Choose all that apply

• Continents fit together like a puzzle

• Land bridges formed

• Mountain ranges from different continents line up when the continents are put together

• There is one continent

Multiple Choice

What evidence from fossils supports the idea that the continents were once joined and then drifted apart?

• Fossils from plants and animals are found on

  two different continents

• Animals swam across the ocean to other continents

• Plants only grew on Pangaea

• Fossils were only found on Pangaea

Multiple Select

What evidence from climate supports the idea that the continents were once joined and then drifted apart? Choose all that apply.

• It was colder at the equator during Pangaea

• Remains of plants and animals are found in

  climates which they could not have survived

• Evidence of

  glaciers are found on continents that are in tropical regions of the Earth.

• Climate change caused the Earth's continents to move

Multiple Choice

Why did other scientists reject Wegener’s idea of continental drift?

• They didn't know that there were continents back then

• He didn't know about Pangaea

• He could not provide an explanation for the force that pushes or pulls the continents

• Wegener was a flat earther

Multiple Select

What evidence did Wegener use to support his ideas about continental drift? Choose all that apply

• Landforms

• Fossils

• Plants

• Climate

• Water
