Which of the following does not cause soil pollution

  1. Acid rain

  2. Agriculture activities

  3. Monsoon rain

  4. Industrial activities

Show answer
Correct Option: C
Explanation:
The following are the main mechanisms that generate soil pollution:
A. Antropogenic – through human activity including:
1. Accidental spills and leaks during storage, transport or use of chemicals (e.g., leaks and spills of gasoline and diesel at gas stations);
2. Foundry activities and manufacturing processes that involve furnaces or other processes resulting in possible dispersion of contaminants in environment;
3. Mining activities involving crushing and processing of raw materials (such as mining activity);
4. Construction activities
5. Agricultural activities involving the spread of herbicides/pesticides/insecticides and fertilizers;
6. Transportation activities (e.g., vehicle emissions)
7. Dumping of chemicals (accidental or intended – such as illegal dumping);
Storage of wastes in landfills (which may leak to groundwater or generate polluted vapours)
8. Cracked paint chips falling from building walls, especially lead-based paint;
B. Natural causes:
1. Natural accumulation of compounds in soil due to imbalances between atmospheric deposition and leaching away with precipitation water (e.g., concentration and accumulation of perchlorate in soils in arid environments).
2. Natural production in soil under certain environmental conditions (e.g., natural formation of perchlorate in soil in the presence of a chlorine source, metallic object and using the energy generated by a thunderstorm).
3. Leaks from sewer lines into subsurface (e.g., adding chlorine which could generate trihalometanes such as chloroform).

Which of the following waste cannot be considered as a soil pollutant?

business organisation and correspondence environmental pollution and industries air pollution and its effects the environment and us environment and conservation

  1. Biodegradable

  2. Non-biodegradable

  3. Industrial

  4. All of the above

Show answer
Correct Option: A
Explanation:

Substances that are not broken down by microorganisms are non-biodegradable. Non-biodegradable substances affect the soil. Biodegradable substances are broken down by organisms and are not harmful to environment. Hence, non-biodegradable and industrial wastes are considered as soil pollutants. They may enter the food chain and harm the organisms in the higher trophic levels. 

Thus, the correct answer is option A.

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

Show answer
Correct Option: A
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.

Soil pollution is caused by

business organisation and correspondence environmental pollution and industries air pollution and its effects the environment and us environment and conservation

  1. Pesticides

  2. Fertilizers

  3. Industrial waste

  4. All of the above

Show answer
Correct Option: D
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

Show answer
Correct Option: C
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

Show answer
Correct Option: A

The type of pollution which occurs in lithosphere is known as

business organisation and correspondence environmental pollution and industries air pollution and its effects the environment and us environment and conservation

  1. Soil pollution

  2. Water pollution

  3. Air pollution

  4. Noise pollution

Show answer
Correct Option: A
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?

business organisation and correspondence environmental pollution and industries air pollution and its effects the environment and us environment and conservation

  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

Show answer
Correct Option: D
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.
