Building Pangea - Continental Drift
Use your "Building Pangea" document that you completed last class to help you with the following questions. Be sure to read the information on the slides between the questions for the "Big Ideas" you should have learned from this activity.
2
Convection currents
Circulation due to the heating and cooling of rock in the mantle creates currents called "Convection Currents"
These currents are what push and pull the tectonic plates, creating movement at plate boundaries.
The direction of these currents is what determines whether two plates, converge, diverge, or slip past one another.
3
Multiple Choice
The circular arrows inside the Earth's Mantle represent what type of motion, that drives ALL plate movement?
4
Multiple Choice
How does heat from the core cause molten rock in these convection currents to move?
5
Multiple Choice
Convection currents beneath the Earth's surface push and pull tectonic plates. Follow the direction of the arrows in the image shown. Imagine the continuous motion of these currents. What type of plate boundary would occur at the surface?
6
The Theory of Continental Drift
In 1915, a German scientist named Alfred Wegener (VAY-guh-ner) proposed the theory of continental drift. According to this theory, the landmasses once were joined into a supercontinent called Pangaea. The landmasses then slowly drifted to their current positions.

Evidence for the Theory of Continental Drift
Fossils, Rocks, Glaciers, and the shape of coastlines are all pieces of evidence that support the theory of continental drift.

Multiple Choice
According to the theory of continental drift, why do the coastlines of Africa and South America appear to fit together so well?
12
Multiple Choice
Lystrosaurus was a slow-moving, plant-eating reptile that lived over 250 million years ago. Fossils of Lystrosaurus have been found in the brown areas shown below. How is this explained by the existence of Pangaea?

Multiple Choice
This is a picture of glacial scratches found in Africa. Which of the following statements best explains the presence of these glacial scratches?
