Plate Tectonics Quiz

Which statement is correct with regard to layers of the Earth.

• Compositional layers are based on how they are chemically composed and structural layers are based on how they behave.

• Structural layers are based on how they are chemically composed and structural layers are based on how they behave.

• Both are correct

• Neither are correct

Which of the following is not one of the compositional layers?

• Core

• Mantle

• Asthenosphere

• Crust

There are two types of crust, continental and oceanic. Which statement best describes these two types of crust?

• Continental is thicker and more dense than oceanic crust

• Oceanic is thicker and more dense than continental crust

• Continental is thicker but less dense than oceanic crust

• Oceanic crust is thicker but less dense than continental crust

Which compositional layer makes up 80% of Earth’s volume?

• Crust

• Mantle

• Outer Core

• Inner Core

• B, D, A, C

• D, B, C, A

What structural layer makes up the tectonic plates?

• Lithosphere

• Asthenosphere

• Mesosphere

• Core

How are the outer core and inner core of the planet different from one another?

• There is no difference between them

• The outer core is made of Oxygen and Silicon and the inner core is made of Iron and Nickel 

• The outer core is solid and the inner core is liquid but the composition is the same

• The outer core is liquid and the inner core is solid but the composition is the same.
