These objects can develop large cracks called berg
These objects can develop large cracks called bergschrunds (BERG-shrunds), which can further lead to the formation of cirques (SIRKS). The firn line separates the ablation and accumulation zones of these objects. The movement of these masses is responsible for the creation of moraines and drumlins, which are accumulations of till carried by these objects. These objects hold the majority of the world's fresh water. For 10 points, name these large, flowing masses of ice.
