The Glenn-Nye law governs these objects' movement,
The Glenn-Nye law governs these objects' movement, which can be facilitated by basal sliding. Areas affected by them are subject to isostatic rebound. They produce chatter marks through plucking, and affected areas are marked by kames and kettles. Sometimes featuring moulins and ogives, these features can form eskers and paternosters. They carve out U- or V-shaped valleys, as well as inlets called fjords, and leave behind drumlins and moraines. Calving on the edges of these objects produces icebergs. For 10 points, name these large frozen rivers of ice.
