Coronal holes are the darker spots when viewed on a x ray picture, ive been doing some reading and it says on many websites that coronal holes create CME but it doesnt say anything about coronal mass ejection and sunspots

Sunspots are related to lower activity of convection in the sun's photosphere due to an increased magnetic activity. Coronal holes are areas in the sun's corona which are colder and has lower density.

Coronal holes are related to solar wind, and there is some correlation between coronal holes and sun spots, but they are not the same phenomena.
