  2. Precipitation

  3. Run-off water

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

Greatest problem in water conservation is to reduce the amount of evaporation. Evaporation is a process by which a large amount of water evaporate in the form of water vapours (gaseous form)

So, the correct answer is 'Evaporation'

Which of the following can be used to conserve water in homes?

  1. Composting toilets

  2. Rainwater harvesting

  3. Automatic faucet

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

Water-saving technology for the home includes:

  • Low-flush toilets and composting toilets. These have a dramatic impact in the developed world, as conventional western toilets use large volumes of water. 
  • Rainwater harvesting high-efficiency clothes washers weather-based irrigation controllers garden hose nozzles that shut off water when it is not being used, instead of letting a hose run. Low flow taps in wash basins. 
  • Automatic faucet is a water conservation faucet that eliminates water waste at the faucet. It automates the use of faucets without the use of hands.

How do you conserve water by watering plants?

  1. By watering optimum quantities regularly

  2. By watering heavily but less often

  3. By watering Twice a week

  4. By watering very little
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Water heavily may  result in root rot due to water logging preventing the roots from respiring aerobically. When roots respire anerobically alcohol produced as a byproduct results in root rot. Watering has to be done based on the season and the water requirement of the plant

So, the correct answer is 'By watering optimum quantities regularly'

An exhaustible renewable resource is

  1. Coal

  2. Solar energy

  3. Water

  4. Petroleum
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Natural resources are of two types, exhaustible and non-exhaustible. Exhaustible resources are those natural resources that are available in limited quantity. Examples include coal, natural gas, petroleum. Non-exhaustible resources are those natural resources that are available in abundance. Renewable resources are those which can be recycled or replenished. The solar energy is renewable and non-exhaustible source. Water is a renewable but exhaustible resource. It may exhaust one day if used without any concern. 

Thus, the correct answer is 'Water.'

  2. 997kg/m3

  3. 897kg/m3

  4. 797kg/m3
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The density of pure water at standard atmospheric pressure and 4 degrees Celsius is approximately 1000 kg/m3. Among the provided choices, 997 kg/m3 is the closest scientific approximation for water at room temperature.

What makes sea water not to be safe for drinking?

  1. High salt concentration

  2. High minerals

  3. Marine water pollution

  4. Density of saewater
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Sea water is unsafe for drinking primarily because of its high salt concentration (approximately 3.5%). Drinking seawater would lead to dehydration as the body requires more water to excrete the excess salt than the water consumed. While other factors like pollution may exist, salinity is the primary reason.
