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.

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.

• 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.

In manufacturing processes, water 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. 

The process by which moisture is carried through plants from roots to small pores on the underside of leaves, where it changes to vapour and is released to the atmosphere is known as transpiration. 

Prolonged reduction of ground-water supplies can have a devastating effect on a farmer’s crop yields. If a drought occurs soon after seeding, plants may fail to germinate; and during the later stages of development, a drought can cause entire crops to wither.

Precipitation in the form of solid particles of snow is known as snowfall. In high latitudinal and temperate regions, snowfall occurs at the mean sea level while in tropical areas, snowfall occurs at place located higher than the snowline altitude.
