Water, in its liquid and solid (ice) states
Water, in its liquid and solid (ice) states, plays a central role in the transformation of geological landscapes. It reacts with rocks and can alter their minerals, while ice also plays a role in the fragmentation of rocks; When freezing in the fissures, the water expands its volume, putting pressure on the rock mass and causing it to break into blocks. Furthermore, water acts as a transport agent, carrying debris resulting from the erosion of rocks by rivers or glaciers over considerable distances.
