How are tectonic plates able to move?
Tectonic plates are moved by convection currents underneath the crust in the mantle.
These convection current is created by molten rock rising, giving off heat and falling back down. This process creates a large swirling current which in turn moves the plates around making them bump around and move (causing earthquakes).
Fun fact, the tectonic plates move 2.5cm per year!

Tectonic plate movement is caused by the process of plate tectonics, which is mainly driven by the forces of ridge push and mantle convection. Ridge push is the gravitational force that pushes the plates away from mid-ocean ridges, where new crust is formed. Other factors that also contribute to plate movement include slab pull, which is caused by the sinking of denser oceanic plates beneath less dense continental plates at subduction zones.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
