Question

Regarding the factors influencing wildfire intensity and characteristics, select the true statements.

1. Many trees in coniferous and evergreen broadleaf forests emit oily or wax-like substances that intensify the fire.
2. The presence of dry fuel does not significantly contribute to the intensity of a wildfire.
3. Once ignited, a wildfire will continue to burn indefinitely unless human intervention occurs.
4. The type of vegetation plays a crucial role in determining the intensity and spread of wildfires.

• A. iv
• B. ii, iii
• C. ഇവയൊന്നുമല്ല
• D. i, iv

Answer 1

Answer:

D. i, iv

• The chemical composition of certain tree species, particularly in coniferous and evergreen broadleaf forests, directly contributes to wildfire intensity. Resins, oils, and waxes present in these trees are highly flammable, acting as natural accelerants. While human intervention can stop fires, naturally, wildfires will continue burning until a significant amount of rain falls or until all available combustible fuel in their path has been consumed, showcasing nature's own mechanisms for cessation.
