In ...................... strategy for saving the environment, things are used again and again.

commercial studies waste products conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources recycling recycling of paper ways to reduce non degradable garbage

  1. Reuse

  2. Invent

  3. Both A and B

  4. None of the above

Show answer
Correct Option: A
Explanation:

In reuse strategy for saving the environment, things are used again and again. Many items found around the home can be used for different purposes. So before you throw those items away, think about how they can be reused.

  4. Russia

Show answer
Correct Option: C

To meet energy crisis what other sources can be exploited?

evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

  1. Wind

  2. Water

  3. Nuclear

  4. All of the above

Show answer
Correct Option: D
Explanation:

The wind, water, and nuclear energy are renewable forms of energy resources. These reserves once consumed can be replenished again. When there is an energy crisis, due to the reduction in the number of energy reserves, there will be an increase in the use of renewable resources. These energy resources can be exploited for the production of energy when there are no other resources available. 

Thus, the correct answer is option D. 

Greatest problem in the water conservation is to reduce the amount of

evs sources of water conservation of natural and energy resources energy conservation and sources reduce, recycle, reuse importance of the conservation of natural resources

  1. Ground water

  2. Precipitation

  3. Evaporation

  4. Run off water

Show answer
Correct Option: C
Explanation:

Evaporation from water reservoirs in hot arid climates causes a loss of 10 vertical feet a year. This water loss can be controlled by construction of reservoirs with greater water depth and concentration of water into single reservoir. Also wind blowing across the surface of water reservoir causes additional evaporation. A windbreak helps to conserve water. Thus the correct answer is option C.

Which one is recyclable waste?

biology garbage in, garbage out recycling of paper ways to reduce non degradable garbage recycling reduce, recycle, reuse

  1. Paper

  2. Torn clothes

  3. Metallic and plastic discards

  4. All the above

Show answer
Correct Option: D
Explanation:
Recyclable wastes can be reused into new materials. For example, paper can be recycled and this will reduce deforestation because the paper is made from wood pulp. Torn clothes can be recycled to form bags and into other usable forms. Metallic and plastic discards can be melted and recycled into usable forms any number of times. Recycling reduces environmental pollution and uses less energy as compared to the production of new materials from raw materials.
Hence, all the options are correct.
So, the correct answer is 'All the above'.
