Continental Drift Quiz

Which layer of earth is composed of liquid iron?

• Crust

• Mantle

• Outer core

• Inner core

Which layer of crust consists of granite?

• Oceanic crust

• Continental crust

• Marine crust

• Pizza crust

Different materials make up Earth. Where would we find the most dense materials?

• In the mantle, the largest layer

• In the crust, which is why we can obtain these materials.

• In the core, the innermost part of Earth.

• In the southern portion of the earth.

If we have not dug past the Earth's crust, how do we predict what state of matter each layer is?

• We used advanced x-ray technology that allows us to see the depths of the layers.

• We monitored seismic waves traveling through Earth's layers.

• We studied volcanoes which spew hot semi-solid and liquid magma.

• We don't actually know and Miss Yee lied to you.

Which scientist first proposed the idea of continental drift?

• Alfred Lothar Wegener

• Harry Hess

• Neil degrasse Tyson

• Marie Tharp

What is the name of the most recent supercontinent?

• Rodinia

• Laurasia

• Gondwana

• Pangaea

The glossopteris (fern plant) found in South America, Africa, and Australia is an example of what type of continental drift evidence?

• Glacial deposits

• Fossil evidence

• Similar rock formations

• Sea floor spreading

Who mapped the ocean floors and what technology did they use?

• Alfred Wegener, echolocation

• Marie Tharp, thermal detectors

• Harry Hess, sonar

• James Watson, hydrosonic vaporizing sensors

One piece of evidence that our sea floor is spreading is

• The newest rocks are found at the mid-ocean ridges.

• The patterns of rocks on each side of the ridges were very different.

• The oldest rocks were scattered throughout the ocean floor.

• The oceanic crust is colliding creating mountains.

Which of the following is evidence of continental drift?

• A dinosaur fossil was found in South Dakota dating back to the Mesozoic Era.

• Similar layers of rocks were found in the Appalachian Mountains and Caledonian Mountains.

• Land bridges connected the coastlines of South America and Africa allowing animals to cross over.

• The Earth has been the same for millions of years and will continue to remain the same.
