Name four factors that help in the formation of soil from rocks.

(N/A) $(i)$ Strong winds: Wind causes erosion and physical weathering of rocks over time.
$(ii)$ Fast-flowing water: Water flowing over rocks causes abrasion and breaks them into smaller particles.
$(iii)$ Living organisms: Lichens,mosses,and fungi grow on rock surfaces,releasing chemicals that break down the rock and contribute to soil formation.
$(iv)$ Temperature variations: Repeated heating and cooling of rocks due to solar radiation causes expansion and contraction,leading to cracks and eventual disintegration.
