Electronic waste is harmful to soil because

  1. They are non-biodegradable waste

  2. They are biodegradable waste

  3. They can be turned into compost

  4. None of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Wastes are mainly of two types, biodegradable and non-biodegradable. Biodegradable wastes are not harmful to soil as they are broken down by microorganisms. Non-biodegradable wastes like hazardous waste, radioactive waste, electronic waste, etc., are harmful to the soil. These are soil pollutants which may enter the food chain and harm the organisms in the higher trophic levels. 

Thus, the correct answer is option A.

  4. All of the above

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil pollution is caused by removal or addition of substances and factors which decrease its productivity. It is caused by agrochemicals, industrial wastes, municipal wastes etc. It adversely affects the fertility of the soil.

Soil pollution is caused by

  1. Water impurity

  2. Smokey air

  3. Chemical deposition

  4. None of the above

Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Soil contamination or soil pollution is caused by the presence of human-made chemicals or other alteration in the natural soil environment. It is typically caused by industrial activity, agricultural chemicals or improper disposal of waste. The most common chemicals involved are petroleum hydrocarbons, polynuclear aromatic hydrocarbons, solvents, pesticides, lead and other heavy metals.

Which of the following is a major cause of soil acidification?

  1. Nitrate Leaching

  2. Nitrification

  3. Soil erosion

  4. None of the above

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Nitrate leaching is a major cause of soil acidification because it removes basic cations (like calcium and magnesium) from the soil, which are then replaced by hydrogen ions.

The type of pollution which occurs in lithosphere is known as

  1. Soil pollution

  2. Water pollution

  3. Air pollution

  4. Noise pollution

Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
The lithosphere is the rigid outer part of the earth, consisting of the crust and upper mantle. The type of pollution which occurs in lithosphere is soil pollution. Soil pollution occurs when the presence of toxic chemicals, pollutants or contaminants in the soil is in high enough concentrations to be of risk to plants, wildlife, humans and of course, the soil itself.
So, the correct answer is 'Soil pollution'.

How do pesticides adversely affect the fertility of soil?

  1. By changing the pH of the soil

  2. By increasing the number of soil microorganism

  3. By decreasing the number of soil microorganism

  4. Both A and C

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil pollution is caused by the addition of substances which decrease its productivity. It is caused by agrochemicals, industrial wastes, municipal wastes etc. It adversely affects the fertility of the soil. Pesticides are used in agricultural practices and these chemicals penetrate into the soil and changes the pH of the soil. Also, pesticides affect the fertility of soil by decreasing the number of soil microorganisms. 

Thus, the correct answer is option D.

Assertion :Suspended particulate matter (SPM) is an important pollutant released by diesel vehicles. 

Reason :Catalytic converters greatly reduce pollution caused by automobiles.

  1. If both the assertion and the reason are true and the reason is a correct explanation of the assertion

  2. If both the assertion and reason are true but the reason is not a correct explanation of the assertion

  3. If the assertion is true but the reason is false

  4. If both the assertion and reason are false

  5. If the assertion is false but reason is true

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

SPM (Suspended Particulate Matter) is defined as particles floating in the air with a diameter below 10um. Studies have shown that high SPM concentrations in the air can have a detrimental impact on respiratory organs. SPM is generated both from natural sources (e.g.,volcanoes or dust storms) and human activities (vehicles, incinerators and industrial plants)

Catalytic converter is a device designed to reduce the amount of emissions from automobiles.The current (so - called three - way) systems use a heated metal catalyst to reduce the emissions of carbon monoxide CO),hydrocarbons and nitric oxide (NO), all of which contribute to the formation of photochemical smog. In an automobile's exhaust system, a catalytic converter provides an environment for a chemical reaction where unburned hydrocarbons undergoes complete combustion. Hence the combustion process continues but outside the engine combustion chamber where no useful energy is extracted.Toxic car gases such as unburned hydrocarbon (UHC) and carbon monoxide(CO) would not exist if the fuel to energy conversion in the engine were perfect.

So, the correct answer is 'If both the assertion and reason are true but the reason is not a correct explanation of the assertion'

Which of the following processes does not increase the amount of carbon dioxide in the air?

  1. Petrol burning

  2. Decay of vegetation

  3. Breathing

  4. Photosynthesis

Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Photosynthesis, process by which green plants and certain other organisms use the energy of light to convert carbon dioxide and water into the simple sugar glucose. In so doing, photosynthesis provides the basic energy source for virtually all organisms. So, the correct option is "D" (Photosynthesis).
