I'm wondering about tectonic activity. Specifically, I want to understand how it occurs, what processes are involved, and what its impacts are on the Earth's surface and environment.

Tectonic plates possess the ability to shift due to the density contrast between the oceanic lithosphere and the asthenosphere.

The oceanic lithosphere, being denser, sinks into the mantle beneath lighter continental lithosphere.

This density difference is crucial in enabling the plates to glide over the weaker asthenosphere.

The asthenosphere, being relatively weak, allows for easier movement of the tectonic plates.

The energy needed to drive plate tectonics originates from the dissipation of heat from the mantle.
