Which of the following statements are true about the Drainage System of the rivers?
(A) The drainage pattern resembling the branches of a tree is known as ‘dendritic’.
(B) The drainage pattern of rivers originating from a hill is known as ‘radial’.
(C) When rivers discharge their waters from all directions into a lake or depression, the pattern is known as ‘centripetal’.

Correct option is D

Correct Answer: (A) and (B)
Explanation:
→ Statement (A): "The drainage pattern resembling the branches of a tree is known as ‘dendritic’." This is true. The dendritic pattern occurs when rivers follow the natural slope of the terrain, resembling a tree structure, where smaller tributaries branch out from larger rivers.
→ Statement (B): "The drainage pattern of rivers originating from a hill is known as ‘radial’." This is true. In radial drainage, rivers radiate outwards from a central point, such as a hill or mountain, forming a pattern resembling the spokes of a wheel.
→ Statement (C): This is not true. The term "centripetal" refers to the movement of objects inwards, like water flowing towards a central point. While this might be part of the description of a lake basin, the drainage pattern itself is called "centripetal" when rivers converge to form a lake or depression, not the other way around.
Information Booster:
→ Dendritic Drainage Pattern: It is the most common type of drainage pattern, where the rivers and their tributaries spread out in a way that resembles the branches of a tree. This type forms when the terrain is uniformly resistant to erosion.
→ Radial Drainage Pattern: This pattern occurs when rivers flow outward from a central point, like the spokes of a wheel. It is typically found in areas with mountains or volcanoes, where the rivers radiate from the peak.
→ Centripetal Drainage Pattern: In this pattern, rivers flow towards a central point, like a depression or lake. It is often seen in areas with closed basins, such as circular valleys.
→ Drainage patterns provide valuable insights into the underlying geology and topography of a region.
→ Trellis Drainage: Another type, characterized by a pattern where the main rivers and their tributaries resemble the grid of a trellis. It occurs in areas with parallel ridges and valleys.
→ Drainage patterns can also help in determining the age of landforms, as older regions tend to have more intricate drainage systems.
