B Correct answer
Explanation

The ratio of the actual specific humidity to the saturated specific humidity at the same temperature.
Degree Of Saturation: It is the percentage of water that occupies the pore spaces present in soil and is said to be a degree of saturation.

Relief Rainfall is also known as __________.

  1. Orographic rainfall

  2. subsistence rainfall

  3. both a and b

  4. none of these

A Correct answer
Explanation

When the moisture saturated air comes across barriers such as mountains, it is forced to ascend and as it rises. Then condensation takes place and rainfall occurs. This type of rainfall is called relief rain or orographic rain.

The degree of saturation varies between __________.

  1. 1 to infinity

  2. 0 to infinity

  3. 0 to 1

  4. none of the above

C Correct answer
Explanation

0 to 1 

The saturated mixing ratio is the maximum amount of water vapor that can be held in the air at a particular temperature. For example, let's say the humidity is 0.8 and the saturated mixing ratio is 0.5. Multiply the mixing ratio by the saturated mixing ratio.

Condensed water vapour falls back to the Earth in various forms. This process is called as _______.

  1. Condensation

  2. Precipitation

  3. Evaporation

  4. None of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

When cloud particles become too heavy to remain suspended in the air, then condensed water vapor falls back to the Earth in various forms. This process is called as precipitation. Precipitation is very important for the life forms on the Earth. The different forms of precipitation are:

  • Rain
  • Drizzle
  • Snow
  • Hail
  • Sleet

The ratio of partial pressure of water vapour in a mixture to the saturation pressure of water at the same temperature of the mixture is called as _________.

  1. humidity

  2. partial humidity

  3. specific humidity

  4. relative humidity

D Correct answer
Explanation
The ratio of the mass of water vapour actually present in certain volume of air (m) to the mass of water vapour (M) required to saturate the same volume of air at the same temperature is called relative humidity (R.H)

Deposition of moisture from the atmosphere on the earth's surface is called __________.

  1. sublimation

  2. precipitation

  3. condensation

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Through the continuous process of condensation, the condensed particles grow in size. They are called water droplets or ices droplets. Due to the force of gravity, these droplets are formed are forced to come down and it is called precipitation. Precipitated moisture falling on the ground takes various forms it can be rain, drizzle, snow, sleet, hail, etc.

It is an opaque cloud in the ground surface layers of the atmosphere.

  1. Mist

  2. Fog

  3. Dew

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

Fog consists of visible cloud water droplets or ice crystals suspended in the air at or near the Earth's surface. Fog can be considered a type of low-lying cloud and is heavily influenced by nearby bodies of water, topography, and wind conditions. In turn, fog has affected many human activities, such as shipping, travel, and warfare.

Visible mass of tiny droplets of water high above the grounds are _________.

  1. raindroplets

  2. clouds

  3. whether

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Cloud has been defined as a visible aggregation of minute water droplets or ice particles in the air, usually above the general ground level. Clouds are the most important form of suspended water droplets caused by condensation. Clouds are generally formed because of adiabatic cooling resulting from the upward movement of air.

Vertical air currents, forms solid ice as _________.

  1. droplets

  2. hail

  3. frost

  4. none of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Vertical air currents form solid ice as Hail.
Hail forms in strong thunderstorm clouds, particularly those with intense updrafts, high liquid water content, great vertical extent, large water droplets, and where a good portion of the cloud layer is below freezing 0 °C (32 °F).
