During which climatic periods would sea levels be lowest?

Explanation:
Sea level changes with how much water is stored on land as ice versus in the oceans. During cold glacial periods, large ice sheets advance and lock a lot of water on land, pulling it out of the oceans and lowering global sea level. In warm interglacial periods, melting ice returns water to the oceans, raising sea level. So the lowest sea levels occur during cold glacial periods.
