Consider the following statements : 1. When rivers originate from a hill and flow in all directions, the drainage pattern is known as trellis pattern. 2. The drainage pattern resembling the branches of a tree is known as centripetal drainage pattern. 3. When the rivers discharge their waters from all directions in a lake or depression, the pattern is known as the dendritic pattern. How many of the statements given above are correct?

Radial pattern

• When streams originate from a hill or a dome and flow away in all directions, the pattern is called radial. The rivers originating from the Amarkantak plateau are an example. Hence, statement 1 is incorrect, as a trellis pattern is one in which the primary tributaries join the main stream at right angles and secondary tributaries run parallel to the main stream.

Dendritic pattern

• The pattern that resembles the branches of a tree, in which the tributaries join the main stream at acute angles, is the dendritic pattern. The rivers of the northern plain are a good example. Hence, statement 2 is incorrect.

Centripetal pattern

• When the rivers discharge their waters from all directions into a lake or a depression, the pattern is called centripetal, as in the Loktak lake of Manipur. Hence, statement 3 is incorrect.
• Therefore, none of the statements is correct.
