Which geological feature is characterized by intense seismic activity?

The correct choice highlights plate boundaries as geological features associated with intense seismic activity. This is primarily due to the movement and interaction of tectonic plates at these boundaries. There are three main types of plate boundaries: convergent, divergent, and transform. At convergent boundaries, plates collide, often leading to earthquakes. Divergent boundaries occur where plates move apart, creating tension and potential seismic activity as magma rises to create new crust. Transform boundaries, where plates slide past one another, are also notorious for generating significant seismic events, such as earthquakes.

Mountain ranges, while often formed by tectonic processes, do not inherently experience intense seismic activity unless they are located near or at plate boundaries. Valleys and basins, on the other hand, are typically areas that experience less seismic activity compared to the movements occurring at plate boundaries. Therefore, plate boundaries are most critical in understanding the link between geological features and seismic phenomena.
