Cycles of freezing and thawing water cause ice wedging, and an ordinary ice road is therefore severely damaged by cracks induced by the traffic. Given these facts, cycles of freezing and thawing water can cause what among the following options:
- clean county roads
 - exposure to cold
 - severely damaged roads
 - Physical weathering
 - colder weather
 - Metling snow
 - smooth safe roads
 - rough riding
