The most responsible factor for any movement in Earth's rock plates is convection currents. These currents occur within the Earth's mantle, where heat from the core causes the molten rock material to rise towards the surface and then cool down, leading to its sinking back towards the core. This continuous movement of material creates a circular pattern known as convection currents, which push and pull the Earth's tectonic plates, causing them to move and interact with each other.
