Convection occurs in the asthenosphere. Plate tectonics depends on heat transfer in the asthenosphere

Explanation:

The asthenosphere is the more plastic, molten layer below the more rigid crust. Crustal blocks like tectonic plates ride across the asthenosphere, being pushed and pulled by the convection (rising hot, sinking cold). The heat transfer helps dictate plate tectonics.
