Question

difference between inland & radial drainage pattern (4-5 points each)​

Answer 1

Hope it helps you !

Radial pattern of drainage

1) Radial drainage pattern, also known as centrifu­gal pattern, is formed by the streams which diverge from a central higher point in all directions.

2)It is obvious that dome structures, volcanic cones, batholiths and laccoliths, residual hills, small tablelands, mesas and buttes, and isolated uplands favour the develop­ment of ideal radial pattern

3)The streams emerge at the central point of the aforesaid reliefs and drain down the slopes in all directions

4)Since the streams follow the slopes and hence they are basically consequent streams

5)These streams resemble the spokes of a wheel or the radii of a circle.

Inland drainage pattern

1. In inland drainage streams join lakes or inland seas.
2. They are fed by rainy water.
3. During rains they experience flash floods.
4. During dry season they get dried up.
5. Less than 10 per cent of the inland drainage is formed by the inland drainage of Rajasthan desert, Aksai chin of Jammu and Kashmir.
