Plate Tectonics Practice

The observation that the continents fit together like puzzle pieces, and may once have been connected, led Alfred Wegener to propose a theory called

• continental plowing.

• continental drift.

• wandering continents.

• shape matching of continents.

Which of the following supported Wegener's theory?

• Matching fossil plant remains found on two different continents.

• Matching reptile remains found on two different continents.

• Nearly identical sedimentary rock types of the same age in widely separated locations.

• All of the above.

Scientists found that the continents were moving apart from each other due to magma rising out of mid-ocean ridges, and they called this

• seafloor spreading.

• seafloor rising.

• changing seafloor.

• underwater volcanoes.

Wegener's old theory, called continental drift, was found to be too simplistic because it did not explain how the continents would move. It was replaced by a theory called

• plate tectonics.

• crustal forces.

• paleomagnetism.

• weather forces.

Plate margins are places where a lot of tectonic activity occur. Earthquakes occur, for example, along convergent margins, where plates are

• moving apart.

• sliding past each other.

• colliding.

Which of the following best describes the location of the mantle?

• Above the crust.

• Between the crust and the lithosphere.

• Between the crust and the core.

• Beneath the core.

Which of the following plate interactions is most likely to form a mountain range?

• A transform boundary between ocean plates.

• A transform boundary between continental plates.

• A convergent boundary between continental plates.

• A subduction zone between a continental plate and an ocean plate.

The boundary at which crust is continually added is a

• subduction zone.

• transform boundary.

• divergent boundary.

• convergent boundary.

Subduction is when

• earthquakes occur along a transform boundary.

• new crust is formed.

• one plate slides under another.

• new islands are formed.

The mid-ocean ridge occurs along a

• convergent boundary where new crust is formed.

• transform boundary where crust is subducted.

• divergent boundary where seafloor spreading takes place.

• divergent boundary where subduction takes place.
