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.'

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.

Which of these methods does not result in conservation of water?

  1. Using drip irrigation

  2. Recycling of water

  3. Cutting vegetation so that less water is lost by transpiration

  4. Planting more trees
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Conservation is the process in which the resources are used in a sustainable manner without affecting the environment. The water resources can be conserved by using drip irrigation which reduces the wastage of water. Recycling of water will help allow usage of the waste water for non-drinking purposes. Afforestation includes planting of more trees increasing the amount of rainfall. Thus, the correct answer is option C.
