Which of the following plays a very important role in causing rainfall?

  1. Factories

  2. Vehicles

  3. Plants

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Transpiration is the process in which plants lose water as water vapor during photosynthesis. This water is added to the moisture in air saturating it and hence generating rainfall. Thus the correct answer is option C.

Water cycles through the biosphere in all of the following processes except     

  1. Precipitation

  2. Condensation

  3. Transpiration

  4. Decomposition

  5. Runoff
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
A. When the water vapour in the atmosphere condenses and fall in the form of rain, hail, snow etc., it is called precipitation.
B. Condensation is the conversion of a gas into liquid when the temperature is lowered down.
C. Transpiration is the loss of water in vapour form from the surface of leaves through minute pores called stomata.
D. Decomposition is the process of breakdown of complex organic materials into simpler ones.
E. Runoff is the overflow or the flow of excess water over the earth's surface from any water source.
Hence, water cycles through the biosphere in all of the given processes except decomposition.
So, the correct answer is 'Decomposition'.

Which of the following processes represents X?
River -> X -> Clouds

  1. Respiration

  2. Transpiration

  3. Combustion

  4. Evaporation
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

In the given figure, X is evaporation. Evaporation is the process of conversion of water into vapour. Water vapour rises up into the atmosphere and cools down to form clouds.

So, the correct answer is option D.

Which of the following explains drought?

  1. Low rainfall than requirement

  2. High rainfall than requirement

  3. Low pressure in atmosphere

  4. High pressure in atmosphere
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A drought is a period of drier-than-normal conditions that results in water-related problems, primarily caused by a significant deficit in expected rainfall.

Which of the following are included in hydrosphere?

  1. Liquid and frozen surface waters

  2. Groundwater held in soil and rock

  3. Atmospheric water vapor

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The hydrosphere is the total amount of water present on the planet which includes the surface water, underground water and in the air (Atmosphere) as water vapor. Hydrosphere can be liquid, ice or vapor. 

So the correct option is 'all of the above'.

The water is bad conductor of electricity.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Distilled water is a bad conductor of electricity as it is electrically neutral. However, tap water is a good conductor of electricity as it may contain some impurities and therefore, the ions flow resulting in the conductivity. So, this statement is "false".
