Continental Drift and Plate Tectonics Lesson

Why was Alfred Wegener unable to explain his theory?

• He couldn't explain how the continents drifted.

• He couldn't explain why similar fossils on different continents were separated

• He couldn't explain why similar geological structures found were found on different continents.

• He couldn't explain why the continents fit together like a puzzle.

The San Andres Fault is an example of a

• convergent boundary

• divergent boundary

• transform boundary

• subduction zone

At which type of boundary do you find most earthquakes form

• divergent boundary between two oceanic plates

• transform boundary between two oceanic plates

• convergent boundary at a subduction zone

• transform boundary between two continental plates sliding past each other

This picture shows

• a transform boundary where one continental crust is sliding past another continental crust

• a convergent boundary where one continental crust is moving towards another continental crust and mountains are forming

• a divergent boundary, where one oceanic crust is moving away from another oceanic crust

• a convergent boundary where one oceanic crust is moving toward a continental crust

This map shows volcanic and earthquake activity. Where is the highest concentration of activity?

• all along the Atlantic Ocean

• all along the Pacific Ocean

• all along the coast of Africa

• all along Indian Ocean

What is the densest type of crust?

• continental crust

• oceanic crust

• mantle crust

• convergent crust

I occur where two plates move past each other in opposite directions.

• transform boundary

• divergent boundary

• convergent boundary

• subduction

I state that Earth's surface is broken into huge, moving slabs of rock driven by motions in the mantle.

• tectonic plates

• Pangaea

• Theory of Plate Tectonics

• continental drift

I'm the name that Alfred Wegener gave to the huge supercontient that he proposed had once existed.

• Pangaea

• Theory of Plate Tectonics

• continental drift

• tectonic plates

I'm the place where two plates converge, or push together.

• divergent boundary

• convergent boundary

• transform boundary

• subduction
