Following are four stages of gully development. Arrange these in order.
a) Healing stage
b) Development stage
c) Stabilization stage
(d) Formation stage
The proper sequence of gully development starts with the Formation stage, followed by the Development stage as erosion deepens. Next is the Stabilization stage, where the gully begins to settle due to reduced water flow and partial vegetation cover. Finally, the Healing stage occurs as vegetation fully stabilizes the gully. Therefore, the correct order is D, B, A, C.
