How is 'soil formation' different from 'soil erosion'? Write two factors responsible for each one of them.

(N/A) Soil formation: It is the process of breaking down rocks into smaller particles through physical,chemical,and biological weathering.
Two factors: $1$. Sun (temperature changes causing expansion/contraction),$2$. Water (flowing water or freezing in cracks).
Soil erosion: It is the process where the top layer of soil is removed or carried away from one place to another.
Two factors: $1$. Deforestation (loss of root binding),$2$. Overgrazing (removal of vegetation cover).
