Continental Drift Review

Continental Drift Review

Station Activity Recap.

Station 1 - Evidence of Continental Drift

• Distribution of Fossils

• Distribution of Glacier Deposits

• Archian Rock Distribution

• Mountain Ranges

• Coal Deposits Across Continents

Multiple Choice

What evidence did Wegener use in his Continental Drift theory?

• Continents and fossils fitting together/matching-up like puzzle pieces

• Plant and animal fossils

• mountain ranges and coal deposits line up across continents

• all of the above

Multiple Choice

How does fossil evidence support Wegener's hypothesis of continental drift?

• Similar fossils are found along continental margins that appear to join together.
• Fossils are found in areas where the present-day climate could not have supported the organisms that made the fossils.
• Similar fossils of giant, land-dwelling dinosaurs are found on continents separated by oceans.
• all of the above

Multiple Choice

Glacier grooves are an example of climate change evidence because?

• glacial grooves are found in Antarctica today and it is cold

• glacial grooves are found in the warm areas today, so it means that continent used to be near the poles

• glacial grooves are found in the cold today and it is closer to the poles

• glacial grooves are found in the warm areas because there was an ice age and continents were never together

Multiple Choice

Coral reefs and coal-forming swamps are found in tropical and subtropical environments, but ancient coal seams and coral reefs are found in locations where it is much too cold today. What does it suggest?

• Wegener suggested that these creatures were alive in warm climate zones and that the fossils and coal later had drifted to new locations on the continents.

• The distribution of coal deposits is uneven around the world.

• The Earth must have gone through a global warming in the past, creating tropical and subtropical climates in places, which are cold now.

• Two continental plates converging

• An earthquake in a subduction zone

• A tectonic plate moving over a hot plate

• Movement at a transform fault boundary

Responsible for mountain range formation.

Multiple Choice

Tectonic Plate movement is caused by ______________.

• convection currents in the mantle

• the moon's gravity

Multiple Choice

The Great Rift Valley in Africa and the Mid-Ocean Ridge were all created by this boundary

• Divergent

• Convergent

• Transform

Modelling a rift valley formation.

Multiple Choice

What is this image of ?

• Divergent boundary

• San Andreas (Transform fault)

• Convergent

Multiple Choice

What kind of plate boundary is shown here?

• divergent

• convergent

• transform

• collision

Station 3 - Convection Current

Convection Tube

Open Ended

How are the convection tube from Station 3 and the Lava Lamp similar? Explain in a paragraph. Do not press ENTER.

Convection current in the mantle is caused by the heat moving up from the core. The warmer, less dense rock material near the core slowly moves upward. Relatively cooler rock from higher in the mantle slowly sinks toward the mantle. As the warmer material rises, it also cools, eventually pushed aside by warmer rising material and sinking back toward the core.
