| | Glaciology - |
 | | Glaciology is the study of glaciers, or more generally the study of ice and natural phenomena that involve ice. |
 | | Areas of study within glaciology include glacial history and the reconstruction of past glaciation patterns, effects of glaciers on climate and vice versa, the dynamics of ice movement, the contributions of glaciers to erosion and geomorphology, lifeforms that live in the ice, and so forth. |
 | | There are two general categories of glaciation which glaciologists distinguish: alpine glaciation, accumulations or "rivers of ice" confined to valleys; and continental glaciation, unrestricted accumulations which once covered much of the northern continents. |
