Detailed explanation-1: -Mosses decrease the impact of pouring rain and prevent soil erosion by forming dense mats on the soil. Mosses develop a mat or carpet-like structure when they grow in dense strands. As a result, they retain a large portion of the falling water, reducing run-off.

Detailed explanation-2: -Mosses along with lichens are the first organisms to colonise rocks and hence, are of great ecological importance. Since mosses form dense mats on the soil, they reduce the impact of falling rain and prevent soil erosion.

Detailed explanation-3: -Solution: Mosses form dense mats on the soil and they reduce the impact of falling rain and prevent soil erosion.

Detailed explanation-4: -Mosses and peat play an important role in permafrost stability by buffering surface soils and permafrost from fluctuating air temperatures. In the growing season, surface soil temperatures are negatively related to the thickness of organic soil layers (Harden et al., 2006; Romanovsky et al., 2008).

Detailed explanation-5: -Mosses form a protective covering over the crumbling soil of cliffs and prevent the rushing rainwater from cutting deeply into the soil. These grow in dense mats so firmly intertwined around the soil particles that there can be little erosion, even on a steep hillside.
