There are several ways in which ice, water, and water vapor can weather/erode mountains and roads:
1) Freeze-thaw weathering: This occurs when water seeps into cracks and crevices in rocks or pavement, and then freezes. As water freezes, it expands and creates pressure, causing the rocks or pavement to crack and break apart. This process is particularly effective in areas with harsh freeze-thaw cycles.
2) Chemical weathering: Water can also dissolve minerals and weak points in the rocks or pavement, breaking them down over time.
3) Erosion: Water can exert a strong force on rocks and pavement, especially during floods or heavy rains. This force can cause soil and rocks to erode away, exposing more and more of the underlying materials.
4) Wind erosion: High winds can erode small particles of rock or sediment from the surface, which can then impact and scratch the surface of roads and mountains.
Overall, water and ice can be powerful agents of erosion and weathering, gradually wearing down mountains and roads over time. With repetition, these erosions can cause significant damage, which requires regular maintenance to keep roads and mountain paths safe.
