| <div class="definition"><div class="short_definition">A mass of [[land ice]], formed by the further recrystallization of [[firn]], flowing continuously from higher to lower elevations.</div><br/> <div class="paragraph">This term covers all such [[ice]] accumulations from the extensive [[continental glacier]] to tiny [[snowdrift glaciers]]. Nearly all glaciers are classified according to the topographical features with which they are associated, for example, highland glacier, [[plateau glacier]], [[piedmont glacier]], [[valley glacier]], [[cirque glacier]]. They are also classified according to their seasonal temperatures, or melting characteristics, as [[temperate glaciers]] or [[polar glaciers]]. If a glacier is flowing, it is active or living; but an active glacier may be advancing or retreating depending upon the rate of flow compared to the rate of [[ablation]] at the terminus. A glacier that has ceased to flow is termed stagnant or dead.</div><br/> </div>
