Multiple Choice

Which layer of the Earth is the outermost layer?

• Crust

• Mantle

• Outer Core

• Inner Core

Multiple Select

Which of the following statements about the Earth's crust are correct? (choose 3)

• It is the outermost layer of the Earth.

• It is the thinnest layer of the Earth.

• It is the most dense layer of the Earth.

• It is less dense than the mantle.

Multiple Select

Which of the following statements about the mantle are correct? (choose 3)

• The mantle is denser than the crust

• The mantle is less dense than the core

• The mantle is the least dense layer

• The mantle is made of molten rock

Multiple Choice

Why is the mantle considered the thickest layer of the Earth?

• Because it contains most of the Earth's mass and is about 3,000 km deep

• Because it is made of water

• Because it is the outermost layer

• Because it is the hottest layer

Multiple Choice

Which layer of the Earth is composed of molten rock?

• Crust

• Mantle

• Inner core

• Outer core

Multiple Choice

What percentage of the Earth's surface is covered by water?

• 50%

• 25%

• 75%

• 90%

Multiple Choice

Which layer of the Earth is directly beneath the crust and what is its main characteristic?

• Mantle; flows with the consistency of asphalt

• Outer core; solid iron and nickel

• Inner core; liquid iron and nickel

• Lithosphere; rigid and brittle

Multiple Choice

Which layer of the Earth is located between the crust and the core?

• Mantle

• Outer core

• Inner core

• Crust

Multiple Choice

Which layer of the Earth is located directly beneath the crust?

• Mantle

• Outer Core

• Inner Core

• Lithosphere

Multiple Select

Select all correct statements about the Earth's mantle. (choose 3)

• It is located beneath the Earth's crust.

• It is composed mainly of solid rock that can flow slowly.

• It is thinner than the Earth's crust.

• It surrounds the Earth's core.

Open Ended

Compare the thickness and density of continental crust and oceanic crust.

Multiple Choice

Which of the following statements about the Earth's crust is correct?

• The continental crust is thicker and less dense than the oceanic crust.

• The oceanic crust is thicker and less dense than the continental crust.

• Both continental and oceanic crusts have the same density.

• The continental crust is younger than the oceanic crust.

Multiple Choice

What is the only liquid layer of the Earth?

• crust

• mantle

• outer core

• inner core

Multiple Choice

Which layer of the Earth is made of liquid nickel and iron?

• Crust

• Mantle

• Outer Core

• Inner Core

Multiple Choice

Why is the inner core solid?

• It's not, it is liquid

• Because of the pressure of the Earth pushing in on it

• Because it isn't hot enough to melt and be a liquid

• Because all of the Earth layers are solid, that's how we can live on it

Multiple Choice

Which layer of the Earth is at the very center?

• Crust

• Mantle

• Inner Core

• Outer Core

Multiple Choice

Which layer of the Earth is made of solid nickel and iron?

• Crust

• Mantle

• Outer Core

• Inner Core

Multiple Choice

What causes a sedimentary rock to change into a metamorphic rock?

• cooling

• melting and freezing

• erosion and pressure

• heat and pressure

Multiple Choice

• sedimentary, metamorphic, igneous

Multiple Choice

Which type of rock is the cooled lava from a volcano?

• metamorphic

• sedimentary
