We need to conserve our natural resources because it is the main source of our daily needs. We need to conserve it because they are limited only. And if these resources are abused and harmed, we will have short quantity of sources for food and living.

If materials will be finished, people will struggle for __________.

  1. electricity

  2. rain

  3. water

  4. none of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The correct option is A if materials will be finished then people will struggle for electricity as it is produced by using coal in the thermal power plant. 


Coal is a fossil fuel which is formed from the accumulated remains of living organisms that were buried millions of years ago. 

Pressure, heat and time allow the organic matter to transform into one of the three major types of fossils fuel, which are coal, oil and natural gas.


Hence, the correct option is A.

A Correct answer
Explanation
A, Inexhaustible resources  are the resources which cannot be finished by human activities such as soil, water and sunlight. 
An inexhaustible resource is a resource that never runs out or gets depleted. Some of such resources include wind, sun, solar energy, tides, and geothermal energy. They are mostly the natural occurring resources hence they reappear naturally.

Industrial boom, increased population and wastage are the causes of _________.

  1. water depletion

  2. oil depletion

  3. coal depletion

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rapid industrialization, population growth, and excessive wastage lead to the over-extraction and pollution of freshwater resources. This combination severely strains local hydrological cycles, causing widespread water depletion.

_____ is a method of conservation of water.

  1. Rainwater harvesting

  2. Rainwater dropping

  3. Rain planning

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Rainwater harvesting is the accumulation and storage of rainwater for reuse on-site, rather than allowing it to run off. Rainwater can be collected from rivers or roofs, and in many places, the water collected is redirected to a deep pit, a reservoir with percolation. Its uses include water for gardens, livestock, irrigation, domestic use with proper treatment, indoor heating for houses, groundwater harvesting.

Cooking food by covering, is the method to save _________.

  1. LPG

  2. CNG

  3. BNG

  4. None of these
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Covering pans keeps the heat in the pan, cooking the food. 


I’ve seen estimates that covered pans consume less than half the energy of uncovered ones, so this is a huge saving both in the amount of LPG used and the heat released in the cabin is used for cooking the food faster.

Hence the option A is correct.

Urbanization, Illegal logging, Agriculture, Subsistence Farming are the causes of ______.

  1. water depletion

  2. forest depletion

  3. both A and B

  4. none of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Both $A$ and $B$ are the results of Urbanization, Illegal logging, Agriculture, Subsistence Farming. 

Water depletion, a term often defined as long-term water-level decline caused by sustained groundwater pumping, is a key issue associated with groundwater use.

Deforestation, clearance or clearing is the removal of a forest. 

Examples of deforestation include conversion of forestland to farms, ranches, or urban use. 

The most concentrated deforestation occurs in tropical rainforests.


Hence the option C is correct.
