Quiz about Unit 5 Review

Question 1

Originally the Continental Drift Theory was not well received by other scientists. Why?

Accepted Answer

The scientists did not know the force responsible for moving the continents

Answer

There was a competing theory at the time which was more believable with more evidence

Answer

There was no numerical data

Answer

The scientists did not fully understand how fossils could be found so far apart

Question 2

What theory stated that Earth's plates are in slow, constant motion but culd not explain how they moved?

Theory of Continental Drift

Answer

Theory of Plate Tectonics

Answer

Theory of Sea-Floor Spreading

Answer

Theory of Convergence

Question 3

What was the new evidence that explained why continents drifted or moved from their original single landmass?

Accepted Answer

Convection currents in the asthenosphere of the mantle were responsible for plate movement.

Answer

Fossil found in Antarctica indicated continent was once near equator

Answer

Landforms found on different continents were composed or made of the same types of rocks

Answer

Sea-floor spreading indicated ocean currents pushed the plates

Answer

oceanic-oceanic

Answer

Question 13

When studying world maps, Alfred Wegener noticed the continents of South America and Africa fit together like puzzle pieces. Which of the following ideas does this observation support?

Accepted Answer

The two continents were once joined in the past and have moved apart since

Answer

The two continents are made of the same type of rock

Answer

The continents have eroded away

Answer

The plates beneath the two continents are the same age

Question 14

Josh had to create a model to represent the theory of plate tectonics for his science class. Which of the following models best describes scientific theory of plate tectonics?

Accepted Answer

Placing two graham crackers over a layer of icing and pushing them together

Answer

Counting the number of pennies that land heads up

Answer

Using a basketball to block the light from a lamp on a ping pong ball

Answer

Mixing vinegar and baking soda together in a flask to see a reaction

Question 15

When two plates converge, what happens depends on the types of crust that meet. Which features are commonly formed at a plate boundary where continental crusts converges with oceanic crust?

Accepted Answer

deep ocean trench and continental mountain/mountain range

Answer

mid-ocean volcanic islands/ deep ocean trench

Answer

volcanic mountain range at the center of the continent

Answer

underwater volcanic mountain/ rift valley

Question 16

In 1927, Alfred Wegener proposed the theory of continental drift which included the supercontinent Pangaea. Later scientists developed the theory of plat tectonics. What are the processes that have been claimed to explain the movements of Earth's tectonic plates?

Accepted Answer

convection in the mantle

Answer

slab pull, and sea floor spreading

Answer

continental drift

Answer

sea floor spreading and ridge push

Accepted Answer

close to mid-ocean ridge

Answer

close to continents

Answer

close to subduction zone

Accepted Answer

earthquakes and volcanic eruptions

Answer

Magnetic pole reversals

Answer

What caused formation of mountain ranges along North and South America?

Accepted Answer

collision of tectonic plates

Answer

erosion of continental tectonic plates

Answer

deposition of river sediments

Answer

Accepted Answer

subduction zone

Answer

rift valley

Answer

strike-slip fault

Answer

divergent boundary
