Drainage Patterns

Choose the Correct Answer

Correct Answer : Option a

Explanation
Statement 1 is correct: Dendritic or tree-shaped drainage pattern is the most common and widespread pattern to be found on the earth's surface. The pattern is called dendritic on the ground that the network of tributaries of various orders and magnitudes of the trunk or master stream resembles the branches and roots and rootlets of a tree.

Statement 2 is not correct: Dendritic pattern develops in a variety of structural and lithological environments such as in the mountainous and hilly areas (e.g. dendritic pattern is one of the dominant patterns in the Himalayas), on extensive plateau surfaces (e.g. Deccan plateau), on peneplain surfaces (e.g. the Peninsular peneplains of India, mostly in the basins of the Mahanadi, the Godavari, the Krishna, the Cauvery, the Damodar etc.), in the alluvial plains (e.g. Great Plains of North India), in the desert plains (e.g. Rajasthan desert), in the glaciated lowland regions (e.g. North European plains and northern lowlands of North America) etc.
