Here's why:
* Divergent Boundaries: These occur where tectonic plates move apart, allowing magma to rise from the mantle and create new crust. This leads to volcanic activity and rift valleys. Hawaii doesn't fit this description.
* Hotspots: These are areas of volcanic activity caused by plumes of unusually hot mantle material rising up through the Earth's crust. The Hawaiian Islands were formed by this process, as the Pacific Plate moved over the stationary hotspot, creating a chain of volcanic islands.
Therefore, Hawaii is not on a divergent boundary, but rather a hotspot.
