The ratio of the mass of water vapor in a given volume (parcel) of air to the mass of the remaining dry air describes the:

  1. Absolute humidity

  2. Mixing ratio

  3. Relative humidity

  4. Dew point

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The mixing ratio is defined as the mass of water vapor divided by the mass of the remaining dry air in a given parcel.

Where does salamander breaded?

  1. Glacial

  2. Melted snow

  3. Oceans

  4. Rivers

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Salamanders breed in melted snow pools and temporary water bodies formed by snowmelt. These spring breeding sites provide essential habitat for egg-laying and larval development. The question appears to ask about breeding habitat, though 'breaded' may be a typo for 'bred'.

The temperature at which water boils depends mainly on:

  1. Air temperature

  2. Relative humidity

  3. Air pressure

  4. Air density

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The boiling point of water is the temperature at which its vapor pressure equals the surrounding atmospheric pressure. Therefore, lower air pressure decreases the boiling point.

The wind flows fromĀ 

  1. High pressure to low pressure

  2. Low pressure to high pressure

  3. Low temperature to high-temperature

  4. All of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The uneven heating of the air causes the flow of the wind. It takes place due to the greater intensity of sunlight at the equator as compared to that of poles. Due to greater intensity of sunlight at the equator the air gets heated up, the air molecules absorb the heat and the intermolecular forces between the air molecules become weak and its kinetic energy increases. The air molecules becomes lighter and rises up. This creates a low pressure zone on the equator while high pressure zone exist at the poles. So, the air moves from high pressure to the low pressure.

So, the correct answer is option A.
