When ice melts in a glass of water the overall level of water in the glass goes down because ice has a higher volume. Would this be true for the oceans then if the ice caps melt and if not why?
The water level in a glass of ice water doesn’t change when the ice melts. Because of buoyancy the ice displaces the same amount of water as it contains. If the ice caps melt the sea level rises because some of the ice is on land and not floating on the ocean.
