One theory is the Sun goes into a ‘cool’ period and doesn’t provide enough energy to the Earth to keep the oceans from freezing............

Thanks. I hadn’t thought about the oceans freezing (at least the upper parts) due to lack of solar radiation. So there wouldn’t necessarily be glaciers on top of the oceans - the oceans just froze up.
