Abstract

This study clarifies the importance of frost action on rock weathering in continental polar climates. A field site was selected in the Ellsworth Mountains of western Antarctica. North- and south-facing walls of the bedrock showed the same shattering rate in the summer of 1992-1993. Frost shattering of rocks is controlled by surface temperature, moisture, and the physical properties of the rock. The most important control on frost shattering in this area was moisture availability, given the same bedrock and freeze-thaw cycle
