What is a activity is directly caused by the motion of tectonic plates?

One activity directly caused by the motion of tectonic plates is the occurrence of earthquakes. As tectonic plates interact—by colliding, sliding past each other, or pulling apart—stress builds up along faults until it's released as seismic energy, resulting in an earthquake. Additionally, this movement can also lead to volcanic eruptions when magma is forced to the surface due to shifting plates.
