What is the primary energy source that drives mantle convection?

• The Sun’s radiation

• Earth’s rotation

• Heat from Earth’s core

• Gravity from the Moon

In mantle convection, hot mantle material rises because it is:

• Denser than surrounding material

• Less dense than surrounding material

• Pulled upward by gravity

• Pushed up by surface pressure

Which feature is most directly formed by mantle convection causing plates to diverge?

• Subduction zones

• Mountain ranges

• Mid-ocean ridges

• Deep-sea trenches

Tags

NGSS.MS-ESS2-3

At convergent boundaries, mantle convection currents typically cause:

• Plates to move apart, forming new crust

• Plates to slide past each other without destroying crust

• Plates to collide, with one plate subducting beneath the other

• Plates to remain stationary

Which statement best explains how mantle convection powers plate tectonics?

• Mantle convection currents drag lithospheric plates along

• Mantle convection currents melt the plates, causing them to dissolve

• Mantle convection currents push continents only, not oceanic plates

• Mantle convection currents stop plate movement

Which of the following best represents the role of density in mantle convection?

• Cooler mantle material rises because it is denser

• Hotter mantle material sinks because it is less dense

• Hotter mantle material rises while cooler material sinks

• Density has no effect

Explain how mantle convection powers the movement of tectonic plates.
