Questions Related to elements of weather and climate : temperature

Determining factors for humidity in the air is, ____________.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Time

  2. Place

  3. Temperature

  4. All of these

Show answer
Correct Option: D
Explanation:

Humidity means the amount of water vapor present in the air. Time, place and temperature play important role in determining humidity. Amount of humidity changes with season and weather variation. Nearness to a water body,i.e, place plays an important role in determining humidity and lastly the moisture-holding capacity of air increases with increasing temperature.

Relative Humidity is more important from Absolute Humidity because __________________.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. It is expressed in percentage.

  2. It is expressed in the ratio of amount of water vapour present in the air at a given temperature and that of amount of water vapour air can hold at that temperature.

  3. Both a and b

  4. None of these

Show answer
Correct Option: B
Explanation:

Relative humidity is expressed as the amount of water vapor in the air as a percentage of the total amount that could be held at its current temperature. Absolute humidity is the measure of water vapor in the air, regardless of temperature. Relative humidity is cited in weather forecasts. It affects how we feel temperature. That’s why relative humidity is important.

The _____________ plays a very important role in heating and cooling the atmosphere.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Water Vapours

  2. Humidity

  3. Precipitation

  4. None of these

Show answer
Correct Option: A
Explanation:

The water vapor is one of the most variable gases in the atmosphere  which is present in small amount but is none the less very important. Water vapor plays an significant role in the insulating action of the atmosphere. The moisture holding capacity of the air varies in the direct proportion to its temperature. In other words the higher the temperature of the air,  the larger the capacity to hold moisture and vice versa. 

These are the droplets of water deposited on any cool surface by condensation of water vapour in atmosphere.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Mist

  2. Fog

  3. Dew

  4. Hail

Show answer
Correct Option: C
Explanation:

The droplets of water deposited on any cool surface by condensation of water vapour in atmosphere are known as dew. When temperature drops and objects cool down, dew is formed. The temperature at which dew forms is called the dew point. Location, weather, and time of day affect the dew point. Dew is more likely experienced by the humid areas than arid areas. It is mostly formed at night.

What is the degree of saturation?

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. The ratio of the actual relative humidity to the saturated specific humidity at the same temperature.

  2. The ratio of the actual specific humidity to the saturated specific humidity at the same temperature.

  3. The ratio of the saturated specific humidity to the actual specific humidity at the same temperature

  4. None of these

Show answer
Correct Option: B
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 __________.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Orographic rainfall

  2. subsistence rainfall

  3. both a and b

  4. none of these

Show answer
Correct Option: A
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

Show answer
Correct Option: C
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 _______.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. Condensation

  2. Precipitation

  3. Evaporation

  4. None of these

Show answer
Correct Option: B
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 _________.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. humidity

  2. partial humidity

  3. specific humidity

  4. relative humidity

Show answer
Correct Option: D
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 __________.

geography hydrologic cycle the atmosphere elements of weather and climate :humidity hydrologic cycle and its components elements of weather and climate : temperature

  1. sublimation

  2. precipitation

  3. condensation

  4. none of these

Show answer
Correct Option: B
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.
