Which BEST describes the density of Earth's layers?

• The crust is the most dense because it is the top layer.

• The mantle is the most dense because it is the thickest layer.

• The outer core is the most dense because it is the only liquid layer.

• The inner core is the most dense because it is under the most pressure.

Which choice describes Earth's crust?

• A thick layer of rock floating on liquid metal.

• A group of continents floating on a large ocean.

• A warm layer of rock floating on a cold layer of rock.

• A thin layer of rock floating on a solid but fluid-like layer.

Which BEST summarizes the composition of Earth's core?

• It contains a solid outer region surrounding a liquid iron core.

• It contains a liquid outer region surrounding a solid iron core.

• It contains a semi-liquid rock outer region surrounding a liquid core.

• It contains a basalt, semi-liquid outer region surrounding a solid core.

Which BEST describes Earth's crust?

• It is stationary and unable to move.

• It is thicker than the mantle and the core.

• It is located between the outer and the inner core.

• It is composed of continental and oceanic plates.

Which causes the movement of tectonic plates?

• Gravitational pull between Earth and the moon.

• Convection occurring beneath the Earth's crust.

• Energy produced by earthquakes within the Earth.

• Rotation of liquid rock found within the core
