What is a techtonic process that generates heat at the boundaries of the plates?

A tectonic process that generates heat at the boundaries of tectonic plates is subduction. In subduction zones, one tectonic plate is forced beneath another into the mantle, where increased pressure and friction generate heat. This heat can lead to the melting of rocks and the formation of magma, contributing to volcanic activity and the creation of mountain ranges. Additionally, the release of energy during plate interactions can cause earthquakes.
