Describe the following drainage patterns of streams:
(i) Radial
(ii) Dendritic
(iii) Trellis (iv) Rectangular pattern
① Dendrite pattern:
It consists of a single main stream with tributaries resembling the branches of a tree. It develops when the river channel follows the slope of the terrain. e.g. Ganga
② Trellis Pattern:
When tributaries join the main stream at right angles, a pattern is called trellis. A trellis drainage pattern develops where hard and soft rocks exist parallel to each other. For example the Narmada.
③ Radial Pattern:
In this pattern, the streams flow in different directions from a central peak or dome like structure forming a radial pattern.
④ Rectangular Pattern:
It develops on a strongly joint rocky terrain. In this, the main stream and its tributaries join at right angles.
How are the West flowing rivers different from the East flowing rivers of Peninsular Plateau? Give any three points of distinction.
