Final answer:
Ridge push is a significant mechanism in plate tectonics driven by mantle convection, influencing plate movements and Earth's surface features.
Explanation:
Ridge push is a process in plate tectonics where the weight of an elevated ridge pushes an oceanic plate toward a subduction zone. This process, along with slab pull, is responsible for plate motion and reshaping the Earth's surface. Mantle convection plays a crucial role in driving these movements through the circulation of hot rock in the Earth's mantle.
