The correct answer is false.
It is false that sea level increases when the number and size of glaciers on Earth increase.
It is exactly the opposite. Sea levels increase when the big glaciers melt. That glacier was frozen water and when it melts down that huge amount of water goes back to the oceans, increasing its level. Global warming is a big factor in the melting of the ice caps in the poles, and this is alarming scientists that tried to create consciousness in major power governments to do something to combat global warming.
