Tectonic Plate Movement and Its Impact on Landforms and Geologic Events

Most geologists think that the movement of Earth’s plates is caused by _______

• convection.

• continental drift.

• subduction.

• conduction.

Answer explanation

Most geologists believe that the movement of Earth's plates is primarily driven by convection currents in the mantle, which create the forces necessary for plate tectonics, making 'convection' the correct answer.

What is the primary mechanism that drives the movement of tectonic plates?

• Wind currents

• Solar energy

• Convection currents in the mantle

• Gravitational pull from the moon

Answer explanation

The primary mechanism driving tectonic plate movement is convection currents in the mantle. These currents are caused by the heat from the Earth's core, creating a cycle that pushes plates apart or pulls them together.
