Why most of the fresh water on earth located in ice caps an glaciers?
Most of the fresh water on Earth is stored in ice caps and glaciers due to the planet's climate and geological history. During the last Ice Age, large volumes of water were trapped as ice in polar regions and high-altitude areas, and this storage mechanism has persisted over millennia. Additionally, these ice formations act as long-term reservoirs, preserving fresh water away from the oceans and making it less accessible for immediate use. As a result, they represent the largest source of fresh water on the planet, significantly outweighing other sources like rivers and lakes.
