Q. Which of the following factors determine the drainage pattern of an area?
1.Topography
2.Periodicity of flow
3.Slope
How many of the statements given above are correct?
Answer: C
Notes:
Explanation: The flow of water through well-defined channels is known as ‘drainage’ and the network of such channels is called a ‘drainage system’.
An area’s drainage pattern is the outcome of the geological time period, rocks’ nature and structure, topography, slope, amount of water flowing and the periodicity of the flow.
