Which of the following forces is NOT involved in plate tectonics?

The correct answer is magnetic pull, as it is not a force that plays a role in the movement of tectonic plates. In plate tectonics, the movement and interactions of the Earth's lithospheric plates are primarily driven by geological processes associated with the mantle's behavior and the dynamics of the plates themselves.

Slab pull refers to the force exerted by a sinking tectonic plate into the mantle at a subduction zone. This process occurs when a denser oceanic plate collides with a continental plate or another oceanic plate, and as it descends, it drags the rest of the plate along with it.

Ridge push is related to the elevated position of mid-ocean ridges, where new oceanic crust is formed. As the lithosphere thickens and cools, it tends to slide down the slope of the ridge, contributing to the movement of tectonic plates away from the ridge.

Mantle convection describes the slow movement of molten rock within the Earth's mantle. Heat from the Earth's core causes the mantle material to rise and cool, creating convection currents that can drag tectonic plates along.

In contrast, magnetic pull does not operate in the context of tectonic plate movements. While the Earth's magnetic field influences various processes, it
