Continental Drift and Plate Boundaries Review

Alfred Wegener’s theory that the continents were once all together forming a single landmass (Pangaea) but have since drifted apart.

Why did Wegener think the continents fit together like puzzle pieces.

• Fossils matched up.

• Mountains matched up.

• The coastlines of Africa and South America are mirror images.

• None of the above.

Why is the location of fossils of reptiles on opposite continents evidence of continetal drift?

• Reptiles were poor swimmers.

• Plant seeds could not move by wind.

• Similar species could evolve at the same time.

• Similar climates.

Where did Wegener find evidence of glaciers supporting his idea of continental drift?

• In arctic regions

• In tropical regions

• All over the world

• He did not find any glacial evidence.

Where did Wegener find evidence coal (formed by tropical plants) supporting his idea of continental drift?

• In arctic regions

• In tropical regions.

• He did not find coal.

• All over the world.

Convergent Boundary

• Plates move apart.

• Plates move together.

• Plates slide past each other.

• Plates do not move.

Subduction

• Less dense plate sinks under more dense plate.

• More dense plate sinks under less dense plate.

• Plates collide and push up.
