Question

Which of the following is/are correctly matched?

• A. Dendritic drainage pattern → uniform substrate and gentle slope
• B. Trellis drainage pattern → parallel valleys and ridges
• C. Radial drainage pattern → uniform flat topography
• D. Rectangular drainage pattern → joints and faults

Hint:

Drainage patterns provide valuable insight into the underlying geology, such as fold structures or fault systems.

Answer 1

The Correct Option is A, B, D

Step 1: Understanding drainage patterns. 
- (A) Dendritic drainage forms in areas with a relatively uniform substrate and gentle slope, so this is correct. 
- (B) Trellis drainage occurs where valleys and ridges are parallel to the flow, usually in areas of folded topography, so this is correct. 
- (C) Radial drainage typically forms from central points, like volcanic cones, rather than from flat topography. 
- (D) Rectangular drainage forms in areas with a network of joints and faults, so this is correct. 
 

Step 2: Conclusion. 
The correct answers:

(A) Dendritic drainage pattern – uniform substrate and gentle slope
(B) Trellis drainage pattern – parallel valleys and ridges
(D) Rectangular drainage pattern – joints and faults
