Unit 3 Part 1 - Earth Science - Midterm Review

From the center of the Earth outward, what are the three layers of Earth?  

• crust - mantle - core
• mantle - crust - core
• core - crust - mantle
• core - mantle – crust

Which of the following is the thinnest layer of the Earth?  

• Crust
• Mantle
• Outer core
• Inner core

What are the two ways in which geologists define the layers of the earth?

• Compaction and solidification
• Physical and compaction
• Physical and compositional
• Solidification and compositional

The Layers of the Earth were mainly discovered by?

• Sending x-ray equipment into fault lines
• Studying seismic waves as they move through earth
• Studying drilled core samples
• Studying the layers of other planets 

The inner core is thought to be made up of?

• Diamonds
• Liquid
• Solid iron and nickel
• Special world filled with magical creatures

What does plate tectonics cause?

• Mountains
• Volcanoes
• Earthquakes
• All of the answer choices.

Who proposed the hypothesis of continental drift?

• Albert Einstein
• Galileo Galilee
• Alfred Wegener
• Steve Irwin

How does finding the Mesosaurus fossil evidence on two separate continents support the continental drift theory?

• because it is unlikely that the Mesosaurus existed on both continents.
• The Mesosaurus fossil evidence does not support the continental drift theory. It proves it wrong.
• because the Mesosaurus lived millions of years ago
• because it is unlikely that the Mesosaurus could swim between continents.

What is the name given by Wegener to the supercontinent he proposed existed before the current continents?

• Euroamerica
• Pangaea
• Gwonondoaland
• Laursia

What is a transform fault boundary?

• A transform boundary is when two plates slide past one another.
• A transform boundary is when two plates collide.
• A transform boundary is when two plates pull away from each other.
• A transform boundary is when two plates move toward each other.
