[[Glacier]]s, while geographically restricted, are effective agents of landscape change. The gradual movement of [[ice]] down a valley causes [[Abrasion (geology)|abrasion]] and [[Plucking (glaciation)|plucking]] of the underlying [[rock (geology)|rock]]. Abrasion produces fine sediment, termed [[glacial flour]]. The debris transported by the glacier, when the glacier recedes, is termed a [[moraine]]. Glacial erosion is responsible for U-shaped valleys, as opposed to the V-shaped valleys of fluvial origin.<ref>{{Cite book|last1=Bennett |first1=M.R. |last2=Glasser |first2=N.F. |date=1996 |title=Glacial Geology: Ice Sheets and Landforms |publisher=[[John Wiley & Sons]] Ltd |page=364 |isbn=0-471-96345-3}}</ref>

The way glacial processes interact with other landscape elements, particularly hillslope and fluvial processes, is an important aspect of [[Plio-Pleistocene]] landscape evolution and its sedimentary record in many high mountain environments. Environments that have been relatively recently glaciated but are no longer may still show elevated landscape change rates compared to those that have never been glaciated. Nonglacial geomorphic processes which nevertheless have been conditioned by past glaciation are termed [[paraglacial]] processes. This concept contrasts with [[periglacial]] processes, which are directly driven by formation or melting of ice or frost.<ref>{{cite journal |last1=Church |first1=Michael |last2=Ryder |first2=June M. |s2cid=56240248 |title=Paraglacial Sedimentation: A Consideration of Fluvial Processes Conditioned by Glaciation |journal=[[Geological Society of America Bulletin]] |date=October 1972 |volume=83 |issue=10 |pages=3059–3072 |doi=10.1130/0016-7606(1972)83[3059:PSACOF]2.0.CO;2 |bibcode = 1972GSAB...83.3059C}}</ref>
