Question

Arrange the Mohr and Van Baren recognized stages of soil development in correct order. A. Virile, B. Juvenile stage, C. Initial stage, D. Senile, E. Final.

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

Hint:

Soil development sequence is Initial \(\rightarrow\) Juvenile \(\rightarrow\) Virile \(\rightarrow\) Senile \(\rightarrow\) Final.

Answer 1

The Correct Option is D

Concept:
Mohr and Van Baren classified soil development into stages based on the degree of weathering and profile development.

Step 1: Initial stage.
Soil development begins with the initial stage, where weathering has just started. \[ \text{First step}=C \]

Step 2: Juvenile stage.
In the juvenile stage, soil formation progresses but the profile is still immature. \[ \text{Second step}=B \]

Step 3: Virile stage.
In the virile stage, soil development becomes mature and active. \[ \text{Third step}=A \]

Step 4: Senile stage.
In the senile stage, the soil becomes highly weathered and old. \[ \text{Fourth step}=D \]

Step 5: Final stage.
The last stage is the final stage. \[ \text{Fifth step}=E \] Thus, the correct order is: \[ C,B,A,D,E \] \[ \therefore \text{Correct Answer is (D)} \]
