Question:
One of the following statements is not true from the point of forests
One of the following statements is not true from the point of forests
Show Hint
Forests narrow the 'Diurnal Range of Temperature'. They prevent the temperature from getting too high in the day AND too low in the night.
Updated On: Aug 20, 2026
- Forests reduce the daily minimum temperature
- Forests increase humidity
- Forests check floods
- Forests can protect society from physical, chemical and noise pollution

Verified By Collegedunia
The Correct Option is A
Solution and Explanation
Step 1: Understanding the Question:
The question identifies a misconception regarding how forests affect local microclimates and environmental health.
Step 2: Detailed Explanation:
• Temperature Moderation: Forests act as a thermal buffer. They reduce the daily maximum temperature (by shading the ground) but they actually increase the daily minimum temperature (at night).
• Radiation Trap: At night, the forest canopy acts like a blanket, trapping the long-wave radiation (heat) emitted from the ground and preventing it from escaping into the atmosphere. This makes the forest floor warmer than an open field at night. Therefore, statement (A) is false.
• Humidity (B): Trees release water vapor through transpiration, which significantly increases the relative humidity of the surrounding air.
• Flood Control (C): The forest floor (litter and humus) acts as a sponge, increasing soil infiltration and slowing down surface runoff, which effectively checks flash floods.
• Pollution Mitigation (D): Trees act as physical filters for dust, absorb chemical pollutants like $SO_2$ and $CO_2$, and act as sound barriers to reduce noise pollution.
Step 3: Final Answer:
Statement (A) is not true because forests moderate temperature by keeping nights warmer (raising the minimum temp) and days cooler.

Statement (I): Anogeissus latifolia is worked only as a component species of mixed forests as coppice-with-standards.
Statement (II): Terminalia arjuna tree is not a regular component of forest stand and is usually worked under selection and coppice with standards.
Choose the correct answer from the options given below: - The most important single factor affecting natural regeneration of Shorea robusta is the time lag between the falling of seed and the commencement of the ________.
- Read the following statements and choose the correct answer about silvicultural system/s adopted for the management of Shorea robusta:
Statement (I): Under clear felling system, a rotation age is fixed and the entire area clear felled and the crop is of uniform age.
Statement (II): Selection system is adopted for areas which are badly eroded and where regeneration is problem and regeneration is obtained by natural means, which may be supplemented by planting.
Statement (III): In coppice with standards system, a few standards are retained and the other trees above the exploitable diameter are clear felled and regeneration is obtained by means of coppice.
