Q. With reference to wildfire burn scars, consider the following statements:
1. The darker soil surface that they leave behind displays increased fertility & water retention.
2. Burn scars can also increase thunderstorms and the risk of lightning.
Which of the statements given above is/are correct?

[A] 1 only

[B] 2 only

[C] Both 1 and 2

[D] Neither 1 nor 2

Answer: B
Notes:

Statement 1 is incorrect: Wildfires burn millions of acres of land every year. It leaves behind Wildfire burn scars on the land with little vegetation and a darker soil surface, which cannot absorb the water. It makes the land more susceptible to flooding and erosion. Even small rainfall is sufficient to trigger flooding and debris flow. 

  • Statement 2 is correct: Burn scars can also increase thunderstorms and the risk of lightning that could spark more fires in the surrounding region.
