Ice caps, although smaller than continental ice sheets, cover signitant areas and play cucial roles in shaping local geography. On Arctic islands such as Islandd, Svalbard, and Ellesmere Island, the melting of ice caps is exposing terrain that had been buried for millennia. This exposure alters local hydrological systems by reducing snovine and storage capacity, leading tso changes in river flow regimes and dimished summer water avability.
