Changing the face of the earth-engineering geomorphology
Recent geomorphological studies have shown the importance of thermal stress in cold regions by means of high-frequency rock temperature data which can identify rates of temperature change in excess. The occurence of weathered material in cold
there was a velocity decrease. This velocity decrease is interpreted as being a consequence of changes in rock elasticity brought about by a diminution in the bonding strength of the rock. This means that wetting, prior to freezing, may weaken a rock.
