During a major ice age, sea levels a) rise because cold water expands. b) fall because ice freezes up out of the water. c) rise because larger icebergs displace more water. d) fall because water evaporates faster in the dry air.

Sea levels drop globally during an ice age (also called a glacial period) as seawater is taken up in the ice sheets. There is decreased evaporation during an ice age and therefore less rain. Ice ages (also called glacial periods) are therefore usually, but not always, associated with an increase in aridity (dryness). So its B. Hope this helps :))
