The correct Answer is
2 and 3 only
Explanation
Drainage patterns describe the geometric arrangement of streams in a drainage basin. These patterns are influenced by factors such as the topography, geology, and underlying rock structure of the region.Statement-wise Analysis
- Dendritic: Incorrect
The description "Rivers discharge waters from all directions into a depression" refers to a centripetal drainage pattern. A dendritic drainage pattern resembles the branches of a tree, where the tributaries join the main river at acute angles, reflecting uniform rock resistance.
- Radial: Correct
A radial drainage pattern occurs when rivers originate from a central elevated point, such as a hill or volcano, and flow outwards in all directions, resembling the spokes of a wheel.
- Trellis: Correct
A trellis drainage pattern develops in regions with folded topography, where hard and soft rocks exist parallel to each other. The primary tributaries flow parallel to each other in the valleys, and the secondary tributaries join them at approximately right angles, cutting across the ridges.
- Centripetal: Incorrect
The description "Resembles the branches of a tree" refers to a dendritic drainage pattern. A centripetal drainage pattern is characterized by rivers converging from all directions into a central depression or lake basin.
