Which of the fossil fuel reserves decrease more rapidly in India

  1. Natural gas

  2. Coal

  3. Petrolium

  4. All


Correct Option: A

The process by which the biodiesel are made is known as

  1. Incubation

  2. Transesterification

  3. Coagulation

  4. Fermentation


Correct Option: B
Explanation:

Transesterification is the process of converting vegetable oil, waste cooking oil and animal fats to biodiesel. In this process glyceride reacts with an alcohol to form fatty acid alkyl esters and alcohol.

So, the correct answer is 'Transesterification'

Jatropha is used for the production of biodiesel because

  1. It can be easily grown under harsh condition

  2. It is a non-edible oil

  3. It is volatile

  4. Both A and B


Correct Option: D
Explanation:

Biodiesel is produced from jatropha oil. Jatropha is used because it is not edible therefore, it will not create problems for humans in terms of food shortage. It also has the ability to withstand drought, naturally, repel pests, and grow in subprime soil and combat soil erosion. Thus, the correct answer is option D.

Oil spill prevention and clean up procedures are monitored by

  1. Navy officers

  2. Environmentalist

  3. Coast guards

  4. None of the above


Correct Option: C
Explanation:

Oil spills occur when liquid petroleum is released into the environment by vehicle, vessel or pipeline. It is mostly seen in water bodies. In water bodies, improper oil extraction due to drilling rigs, offshore oil platforms and well result in oil spills. Oil spill prevention and clean up procedures include the use of dispersants to break down the oil, collect oil from the surface of the water using a skimmer or use of biological agents. These procedures are monitored by coast guards. Thus, the correct answer is option C.

Leakage of oil tanks and improper oil extraction can cause

  1. Biomagnification

  2. Oil spills

  3. Air pollution

  4. None of the above


Correct Option: B
Explanation:

Oil spills occur when liquid petroleum is released into the environment by vehicle, vessel or pipeline. It is mostly seen in water bodies. Crude oil is released by tankers on land thus leading to oil spills. In water bodies, improper oil extraction due to drilling rigs, offshore oil platforms and well result in oil spills. Thus the correct answer is option B.

Which of the following is fossilized remains of organic materials?

  1. Natural gas

  2. Petrol

  3. Gold

  4. Both A and B


Correct Option: D
Explanation:
A fossil is the remains of a once-living plant or animal that was preserved in rocks or other materials. It includes fossil fuels (oil, coal, petroleum, and natural gas) that have been formed from the remains of these dead plants and animals.It includes bones or shells of animals and leaves, seeds, or woody parts of plants. Which are subjected to tremendous pressure, heat and other conditions that convert them into fossil fuels.
So, the correct answer is 'Both A and B'

Find the odd one out.

  1. Bioalcohol

  2. Green diesel

  3. Bioethers

  4. Petroleum


Correct Option: A

It is possible to extract maximum energy from wood through 

  1. Biomass

  2. Cracking

  3. Direct burning

  4. Gasification


Correct Option: D
Explanation:

Gasification is an efficient means of converting low value fuels and residuals into a synthesis gas (or syngas). Syngas is used to produce power, steam, hydrogen, and basic chemicals such as methanol and ammonia.

Cultivation of more fuel wood trees is known as

  1. Afforestation

  2. Energy plantations

  3. Energy cropping

  4. Deforestation


Correct Option: B
Explanation:

Energy plantation means growing selected species  of  trees and shrubs which are  harvestable in a comparably  shorter time and are  specifically meant for fuel. The fuel wood may be used either directly in wood burning stoves and boilers or processed into methanol, ethanol and producer gas. These plantations help provide wood either for cooking in homes or for industrial use, so as to satisfy local  energy  needs in a decentralized manner.

The most abundant fossil fuel is

  1. Natural gas

  2. Petrol

  3. Diesel

  4. Coal


Correct Option: D
Explanation:
Fossil fuels are obtained from organic matter that has decomposed under the intense pressure and heat of the earth's crust. According to a data published in 2013 by the International Energy Agency, coal was found to be the most abundant fossil fuel. Thus, the correct answer is option D.
