What geological activity primarily occurs along tectonic plate edges?

Geological activity that primarily occurs along tectonic plate edges is characterized by earthquakes. This is because the edges of tectonic plates are areas where the plates interact with each other, which can involve sliding past, colliding, or pulling apart. When stress builds up along these plate boundaries due to the movement of the tectonic plates, it is released suddenly, resulting in seismic waves that we experience as earthquakes. This tectonic activity is most pronounced at the edges, where the various types of plate boundaries—such as convergent, divergent, and transform—play a crucial role in the frequency and intensity of earthquakes.

In contrast, weathering, erosion, and deposition are processes related to the breakdown and movement of materials on the Earth's surface rather than being directly linked to the tectonic activities. Weathering involves the physical and chemical processes that break down rocks, erosion refers to the removal of material from one location to another by agents like water or wind, and deposition is the process where sediments are laid down in new locations. While these processes do have geological significance, they do not occur specifically as a result of tectonic plate interactions.
