Earth's Layers

What are the two types of crust?

• top crust,bottom crust
• oceanic crust, continental crust
• water,land
• none of the above 

Scientists determine what Earth’s interior looks like by using:

• Volcanoes
• Seismic Waves
• Continental Drift
• Convection Currents

The solid, outer layer of the Earth that consists of the crust and the rigid upper part of the mantle

• Lithosphere
• Mesosphere
• Mantle
• Crust

Which earth layer is #2?

• Crust
• Mantle
• Outer core
• Inner core

Which earth layer is #3?

• Crust
• Mantle
• Outer core
• Inner core

Large pieces of lithosphere that move around on the asthenosphere are called

• Crust plates
• Tectonic plates
• Mantle pieces
• Core plates

NGSS.MS-PS3-4

Which of the following statements is TRUE?

• The inner core is less dense than the outer core.

• The continental crust is denser than the oceanic crust.

• The oceanic crust is denser than the continental crust.

• The lower mantle is less dense than the asthenosphere.

What causes the inner core to be solid despite the extreme temperature at the depth in which it found?

• Extremely high pressure

• Extremely low temperature

• Extremely high temperature

• This is false, because the inner core is liquid.
