Here are a few more for them to answer.
What caused the ice ages?
Why is our magnetosphere loosing it’s field strength?
Why does our sun go through solar max and revers polarity every 11 years?
Why has the earth reversed polarity so many times in the past?
Why is the magnetic north pole representing the top of the axis of the earth’s core slip against the crust and travel around the geographic north pole?
Why does the magnetic north pole and the earth’s core axis have a daily wobble of approximately 85 kilometers per day as it traverses across Canada? And, why does this wobble directly correlate to the peak solar activity?
Why were there active volcanoes in Arizona(north of Flagstaff) about 1200 years ago but not now?
The list goes on.... but not for emotional decision makers as they will shoot any messenger that asks questions of which the answers might bring facts to the surface that are contrary to their predisposed opinion.
