Question

1. what is one of the main drivers of todays plate tectonics?

○ subduction
○ conduction
○ divergence
○ mantle convection

Explanation:

Plate tectonics is driven by heat transfer in Earth's mantle. Mantle convection refers to the slow movement of semi-solid mantle material due to heat from the core—warmer material rises, cools, and sinks, creating currents that pull tectonic plates. Subduction, divergence, and conduction are related processes but not the main driver: subduction is a plate interaction, divergence is a plate boundary type, and conduction is a less efficient heat transfer method compared to convection.

Answer:

D. mantle convection
