Multiple choice evs how to save fuel define fossil fuels conservation of fuels reason for finishing of materials (resources)

Which of these is not a fossil fuel?

  1. Coal

  2. LPG

  3. Bio gas

  4. All are fossil fuel
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

LPG is a fossil fuel which contains low carbon. It is a fossil fuel that does not occur during isolation. LPG is found naturally in combination with other hydrocarbons, crude oil, and natural gas. LPG is produced during natural gas processing and oil refining process.

Coal and Natural gas are also the fossil fuels and are obtained from earth crust.

Biogas is a mixture of methane ,carbon dioxide ,hydrogen and hydrogen sulphide. it is produced by anaerobic degradation of animal waste such as cow dunk in presence of water.

Hence options C  is correct.

What is the cause of a very high demand of water even though it is inexhaustible natural resource?

  1. Fresh water makes only small volume of world's water

  2. Most of the fresh water is in the form of ice and snow cover

  3. Conversion of sea water to fresh water is difficult and not economical

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

Water is inexhaustible natural resource .i.e. it is never going to deplete but it has a very high demand because the large percentage of water which is present on the Earth surface is not suitable for drinking. The suitable form is in the frozen form (ice, snow, glaciers etc). Its conversion to drinking water is non-economical and hence is not favoured.

A natural resource is anything that people can use which comes from nature. People do not make natural resources, but gather them from the earth. A non-renewable resource is a resource that does not grow and come back or a resource that would take a very long time to come back. For example, coal is a non-renewable resource.

Which of the following is a non-renewable resource?

  1. Tidal energy

  2. Wind

  3. Petroleum

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

A non-renewable resource does not renew itself at a sufficient rate for sustainable economic extraction in meaningful human time-frames. Earth minerals, metal ores, fossil fuels and groundwater in certain aquifers are all non-renewable resources.
In contrast, resources such as timber and wind (used to power energy conversion systems) are considered renewable resources.
