Question

which statement describes the process of subduction?
convection currents cause two plates to move away from each other.
a plate slides beneath another plate due to convection currents and gravity.
materials are heated and transferred within earths interior by density.
heat cycles in the mantle cause plates to constantly move.

Explanation:

Subduction is a geological process where one tectonic plate moves under another. Convection currents in the mantle and gravity play a role in this movement. The first option describes divergence (plates moving apart). The third option is about heat transfer within the Earth's interior but not specifically subduction. The fourth option is about plate movement in general due to mantle heat cycles. The second option correctly describes a plate sliding beneath another (subduction) due to convection currents and gravity.

Answer:

A plate slides beneath another plate due to convection currents and gravity.
