Nettet3. apr. 2024 · No, the underlying rock need not have a surface temperature above 0 deg C. Friction between a moving ice mass and the underlying rock causes heat energy to be generated which in turn causes a phase change, ie ice melt, still at 0 deg C … which in turn causes a reduction in friction because liquid water is a lubricant … hence the … Nettet12. sep. 2024 · Ice sheets and ice caps take the same basic form, having a broad, upstanding, and slowly moving ice dome at their centre, with channels of faster moving ice that transfer mass to their margins.

Glacial Movement: Definition, Types & Process StudySmarter
NettetGlaciers, also known as “rivers of ice,” actually flow. Gravity is the cause of glacier motion; the ice slowly flows and deforms (changes) in response to gravity. A glacier molds itself to the land and also molds the land as it creeps down the valley. Many glaciers slide on their beds, which enables them to move faster. Nettet'moving ice mass' is the definition. (I've seen this before) This is the entire clue. (Other definitions for glacier that I've seen before include "One creeps downhill" , "Creeping … chigger red mama cried
