According to the theory of continental drift, why do the coastlines of Africa and South America appear to fit together so well?

• Africa and South America used to be joined together, but split apart long ago.

• Africa and South America are drifting towards each other and will soon fit together perfectly.

• Ocean currents on either side of the Atlantic have eroded the coastlines into the same shape.

• The theory does not explain why the coastlines seem to match.

What evidence supports the idea that all the continents were once joined together?

• Similar rocks found on different continents.

• Mountains created by colliding continents.

• Evidence of glaciers in unexpected places.

• All of the above.

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?

• Lystrosaurus swam across the oceans from one continent to another.

• Lystrosaurus drifted on rafts of vegetation from one continent to another.

• and bridges once crossed oceans to connect Africa, Antarctica, and India.

• Africa, Antarctica, and India used to be joined together into a single landmass.

Which boundary or zone adds new material to the lithosphere (the hard outer crust of the Earth)?

• Subduction zone

• Divergent boundary

• Collision zone

• Transform boundary

In what way does a transform boundary differ from the other boundary types?

• Transform boundaries are always found on the ocean floor.

• Transform boundaries can result in volcanic activity.

• At a transform boundary, one plate slides beneath the other.

• At a transform boundary, the plates move in a direction that is parallel to the boundary line.

The highest mountains in the world are the Himalayas, at the border between the Indian and Eurasian plates. The Himalayas formed in a ________________.

• subduction zone

• divergent boundary

• collision zone

• transform boundary
