Geography India - Water bodies

Consider the following statements:

1. Drainage patterns reflect the structure of the rock.

2. Dendritic drainage patterns develop when underlying rock offers non-uniform resistance.

3. Radial drainage patterns develop surrounding areas of high topography where elevation drops from a central high area to surrounding low.

4. Rectangular drainage patterns develop where linear zones of weakness, such as joints or faults cause the streams to cut down along the weak areas in the rock.

The correct combination of statements is:

1, 3 and 4

1, 2 and 3

3 and 4

1 and 2

Explanation:

2nd statement is incorrect i.e. Dendritic drainage patterns develop when underlying rock offers non-uniform resistance.
A dendritic drainage pattern occurs when the tributary systems subdivides headway like the limbs of a tree. These patterns usually form in horizontal sedimentary or in intrusive igneous rocks where the rock mass is reasonably homogeneous.
