Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Concept:
Water erosion includes detachment and transport of soil particles by rain, runoff and related water movement processes.
Step 1: Rain splash and hail impact erosion.
Raindrops and hail impact detach soil particles. \[ A \text{ is correct} \]
Step 2: Runoff erosion.
Runoff water transports detached soil particles. \[ B \text{ is correct} \]
Step 3: Snow thaw erosion.
Snow thaw may also contribute to water erosion in certain regions. \[ C \text{ is correct} \]
Step 4: Chemical erosion and suspension.
Chemical erosion is not a standard component of mechanical soil loss by water erosion in this classification. Suspension is more commonly discussed as a transport process in wind erosion. \[ D \text{ and } E \text{ are not selected} \] Thus: \[ A,B,C \] \[ \therefore \text{Correct Answer is (B)} \]
