Q. Consider the following statements:
1. The drainage pattern resembling the branches of a tree is known as “radial” pattern.
2. The primary tributaries of rivers flow parallel to each other, and secondary tributaries join them at right angles, the pattern is known as ‘trellis’
3. The rivers originate from a hill and flow in all directions is known as “dendritic” pattern.
How many of the statements given above is/are not correct?
Answer: A
Notes:
Explanation: Important Drainage Patterns
(i) The drainage pattern resembling the branches of a tree is known as “dendritic” the examples of which are the rivers of northern plain.
(ii) When the rivers originate from a hill and flow in all directions, the drainage pattern is known as ‘radial’. The rivers originating from the Amarkantak range present a good example of it.
(iii) When the primary tributaries of rivers flow parallel to each other and secondary tributaries join them at right angles, the pattern is known as ‘trellis’.
(iv) When the rivers discharge their water from all directions in a lake or depression, the pattern is known as ‘centripetal’.
