Question

Arrange these gully development stages in a sequence. A. Development stage, B. Healing stage, C. Formation stage, D. Stabilization stage.

• A. B, A, C, D
• B. C, A, B, D
• C. D, B, C, A
• D. A, B, C, D

Hint:

Gully development sequence is formation, development, healing and stabilization.

Answer 1

The Correct Option is B

Concept:
A gully passes through different stages from its beginning to stabilization.

Step 1: Formation stage.
The first stage is formation, where the gully starts developing due to concentrated runoff. \[ \text{First step}=C \]

Step 2: Development stage.
After formation, the gully deepens and widens. \[ \text{Second step}=A \]

Step 3: Healing stage.
Later, vegetation and deposition may start healing the gully. \[ \text{Third step}=B \]

Step 4: Stabilization stage.
Finally, the gully becomes stabilized. \[ \text{Fourth step}=D \] Thus, the correct sequence is: \[ C,A,B,D \] \[ \therefore \text{Correct Answer is (B)} \]
