The circulation of material caused by differences in density is called convection.

• True
• False

As new seafloor moves away from an ocean ridge, the seafloor cools and becomes less dense than the material beneath it.

• True

The weight of a subducting plate helps to pull the lithosphere into a subduction zone in a process called ridge push

• True
• False

Scientists at the time rejected Wegener’s hypothesis of continental drift because he could not explain how or why Earth’s continents move.

• True
• False

According the theory of plate tectonics, plates interact at plate boundaries by deflecting each other, moving away from each other, or moving horizontally past each other.

• True
• False

If two continental plates converge, a subduction zone forms.
