The boundary between the Nazca Plate and the Pacific Plate is primarily a divergent boundary, where the two plates move away from each other.
This area of divergence is located in the southeastern Pacific Ocean, and it is responsible for the formation of new oceanic crust as magma rises to the surface. This process occurs at mid-ocean ridges, where tectonic activity is prevalent.
The interaction between the Nazca Plate and the Pacific Plate also contributes to various geological features, including the formation of underwater mountains and potential volcanic activity. Over time, the movement of these plates shapes the ocean floor and influences seismic activity in the region.
