Discussion
Read the following statements :
Assertion (A) : Deforestation can lead to floods.
Reasoning (R) : The infiltration rate of water is reduced due to deforestation.
Choose the correct option.
Answer: A
Both (A) and (R) are true and (R) is the correct reasoning for (A).
Trees and their roots hold the soil, slow down rainwater and, with the humus they add, help water soak into the ground. When forests are cut, infiltration falls: more rainwater runs off the surface at once into streams and rivers, which can overflow and cause floods. Soil eroded from bare land also silts up river beds, adding to flooding.
So deforestation can lead to floods, and reduced infiltration is the reason it does. Options B, C and D deny that the two are true or linked.
