Answer:
Every one except 4
Step-by-step explanation:
Volcanoes are very common in hotspots, as well as the formation of geysers and mud pots. The Hawaiian Islands are located right in the middle of a plate and right over a hotspot, so that means that hotspots don't only from on the plate boundaries. Yellowstone National Park is a geothermal hotspot where geysers form. I hope this helps you!
