Why is the sealevel so low during ice age?
Ice is frozen water. It is evident that if a lot of the land is covered with ice then that ice had to come from somewhere. The only places it could come from are the oceans. Water evaporates from the oceans, it falls on high ground as snow and over time this compacts into ice. If water is being evaporated from the oceans and none is being returned then the water level drops.
