Convection currents.
Plate
In seafloor spreading, the old crust moves away from the mid-ocean ridge as new crust forms through volcanic activity. This movement is driven by the process of mantle convection, where hotter and less dense material rises at the ridge, pushing the tectonic plates apart. As new crust forms at the ridge, it gradually moves away from the ridge as more magma is added, creating a conveyor belt-like system of crustal movement.

Oceanic crust is generally younger than continental crust. Oceanic crust is continuously formed at mid-ocean ridges through volcanic activity and then gradually moves away from the ridge, undergoing processes that make it relatively young compared to the older continental crust.
At a destructive margin, also known as a convergent boundary, two tectonic plates collide. One plate is usually forced beneath the other in a process called subduction. This can result in the formation of deep ocean trenches, volcanic arcs, and earthquakes.

The crust moves on a plastic like layer of the mantle.
The crust moves on a plastic like layer of the mantle.
The crust moves like globe, for example. you know how there is rings around it? that will be the crust and the ball will be the mantle. Spin the rings, not the globe. the crust moves AROUND the mantle

A sudden movement of the Earth's crust is called an earthquake.
