Question

Which one of the following describes the drainage patterns resembling the branches of a tree?
A. Radial
B. Dendritic
C. Centrifugal
D. Trellis

Answer 1

Hint: The pattern formed by streams, river and lakes in a particular drainage basin is called the drainage pattern. The major factor which determines the kind of drainage pattern is the topography of the region.

Complete Answer:The dendritic drainage pattern is the drainage pattern which resembles branches of a tree. Such a drainage pattern is produced when a stream has received water from several tributaries which in turn have been fed by smaller tributaries.

The dendritic drainage pattern is also the most common type of drainage pattern. Dendritic drainage patterns occur in areas where the rocks which are present beneath the stream have no particular structure and therefore they can be eroded easily in all directions.

Option A - Radial - In this type of drainage system the streams flow outward from a central high point. In India such drainage patterns can be seen in the Amarkantak range.

Option C - Centrifugal - It is just the opposite of the radial drainage pattern. In it all the streams flow inwards ending with a depression.

Option D - Trellis - It is common to a common garden trellis. In it smaller tributaries enter the main river about perpendicular which causes a trellis like appearance of the system.

Therefore the correct answer is option B.

Note: Drainage systems are also known as river systems. As per how the channels are lying, drainage systems fall into many categories and these categories are known as drainage patterns.
