1 Answer

Answer :

(4) All of the above Explanation: Floods are caused by a variety of factors, both natural and man-made. Apart from soil erosion and silting of river beds which force the water of rivers/streams to spill over, deforestation has lately been a key factor in fostering recurrent floods. The presence of trees act as checks against water flow and in turn protect the underlying soil from getting eroded and then getting washed away.
