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

  1. Mist

  2. Fog

  3. Dew

  4. Hail


Correct Option: B
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


Correct Option: B
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


Correct Option: B
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).

Hygrometer is the instrument used to measure _________.

  1. rainfall

  2. temperature

  3. humidity

  4. none of these


Correct Option: C
Explanation:

Humidity,

A hygrometer is a weather instrument used to measure the humidity in the atmosphere. There are two main types of hygrometers -- a dry and wet bulb psychrometer and a mechanical hygrometer.

Rainfall due to cyclones and depressions is ___________.

  1. clouds

  2. relief rainfall

  3. cyclonic rainfall

  4. none of these


Correct Option: C
Explanation:

In a cyclone, the winds from all directions converge at the centre. Air with different temperature meets at the center. The cold air pushes the warm air upward which gets cool as it moves up and precipitation occurs.  So rainfall due to cyclones and depression is termed as cyclonic rainfall.

Dew is formed when ____________________.

  1. the wind is too dry to cause rainfall

  2. the moisture from air is deposited on a cool surface

  3. the sky is overcast at night

  4. None of these


Correct Option: B
Explanation:

Tiny drops of water that form on cool surfaces at night, when atmospheric moisture gets deposited on the cool surface, is called dew. Thus option B is correct.

Which of the following statements is incorrect?

  1. Cyclones are accompanied by strong winds and heavy rainfall

  2. Anti-cyclones create fair weather conditions

  3. Sea breeze is that local wind which blows during the day from the sea to land

  4. Land breeze is that local wind which blows for twenty-four hours from the land to the sea


Correct Option: D
Explanation:
  • A land breeze is a breeze blowing towards the sea from the land, at night, owing to the relative warmth of the sea. It blows only in the night and not for 24 hours, thus option D is the answer as the statement is wrong.
  • Rest statements are true, hence cannot be the answer.

Find the odd one out and give explanation of your choice.

  1. Evaporation

  2. Condensation

  3. Salination

  4. Precipitation


Correct Option: C

Most villages in India draw water from ______ and ______.

  1. Wells

  2. Tubewells

  3. Driven wells

  4. Both and b


Correct Option: D

Water is required for ______ processes.

  1. Finishing

  2. Manufacturing

  3. Packaging

  4. Both a and b


Correct Option: B
Explanation:

In manufacturing processeswater is used to generate electric power, to make steam for processing and cleaning, to cool or control process temperature, to rinse, to dilute food, and to formulate products containing water.
