Which of the following weather elements always decreases as we climb upward in the atmosphere?

  1. Wind

  2. Temperature

  3. Pressure

  4. Moisture
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Atmospheric pressure is the weight of the air column above a point. As you climb higher, there is less air above you, so the pressure must decrease.

Humidity influences corrosive action of

  1. Air pollutants

  2. Water Pollutants

  3. Solid material

  4. All of above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Humidity, specifically the presence of water vapor, accelerates the oxidation process of metals and reacts with air pollutants to form corrosive acids, which damage materials.

The time of day when the relative humidity reaches a maximum value is usually:

  1. At the time when the air temperature is highest

  2. In the middle of the afternoon

  3. At the time when the air temperature is lowest

  4. Just before sunrise
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Relative humidity is inversely related to temperature. Since the air temperature is usually lowest just before sunrise, the relative humidity reaches its maximum value at that time.

Suppose saturated polar air has an air temperature and dew point of $-10^{o}C$, and unsaturated desert air has an air temperature of $35^{o}C$ and a dew point of $10^{o}C$. The desert air contains ____________ water vapor and has a ____________ relative humidity than the polar air.

  1. More, lower

  2. More, higher

  3. Less, lower

  4. Less, higher
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The desert air has a dew point of 10C, while the polar air has a dew point of -10C. Since dew point is a measure of absolute water vapor content, the desert air has more water vapor. However, because the desert air is much warmer, its capacity to hold water is much higher, resulting in a lower relative humidity.

The temperature scale where 0o represents freezing and $100^{o}$ boiling :

  1. Fahrenheit

  2. Celsius

  3. Kelvin

  4. Absolute
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The Celsius scale is defined by the freezing point of water at 0 degrees and the boiling point at 100 degrees at standard atmospheric pressure.

Temperature of a particular region determines the 

  1. Distribution of flora

  2. Distribution of fauna

  3. Texture of soil

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Temperature is a critical environmental factor that dictates the survival, distribution, and metabolic rates of both flora (plants) and fauna (animals).
