Exploring Earth's Layers Quiz

What is the primary composition of Earth's inner core?

• Iron and nickel

• Silicon and oxygen

• Magnesium and aluminum

• Carbon and hydrogen

Which layer of the Earth is liquid and surrounds the inner core?

• Crust

• Mantle

• Outer core

• Lithosphere

Describe the difference in composition between the continental crust and the oceanic crust.

• Continental crust is denser than oceanic crust.

• Oceanic crust is primarily composed of granite, while continental crust is basaltic.

• Continental crust is primarily composed of granite, while oceanic crust is basaltic.

• Both crusts have the same composition.

What is the main component of the Earth's mantle?

• Iron

• Silicate minerals

• Nickel

• Carbon dioxide

Explain how the lithosphere differs from the asthenosphere.

• The lithosphere is rigid and brittle, while the asthenosphere is semi-fluid and can flow.

• The lithosphere is semi-fluid and can flow, while the asthenosphere is rigid and brittle.

• Both the lithosphere and asthenosphere are rigid and brittle.

• Both the lithosphere and asthenosphere are semi-fluid and can flow.

What is the approximate temperature range of the Earth's inner core?

• 500°C to 1,000°C

• 1,000°C to 2,000°C

• 3,000°C to 5,000°C

• 5,000°C to 7,000°C

Identify the layer of the Earth that is responsible for generating the planet's magnetic field.

• Crust

• Mantle

• Outer core

• Inner core

How does the composition of the mantle affect its physical properties?

• The high iron content makes it magnetic.

• The silicate minerals allow it to be semi-solid and capable of slow flow.

• The high water content makes it liquid.

• The carbon content makes it brittle.

What is the primary difference between the Earth's crust and mantle?

• The crust is thicker than the mantle.

• The mantle is composed of lighter elements than the crust.

• The crust is solid, while the mantle is liquid.

• The crust is composed of lighter elements than the mantle.

Which type of crust is denser, oceanic or continental?

• Oceanic

• Continental

• Both have the same density

• Neither has density
