Questions Related to environmental risks of economic development

The two gases making highest relative contribution to the greenhouse gases are ____________________.

geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

  1. methane and carbondioxide

  2. butane and carbondioxide

  3. propane and carbondioxide

  4. ethane and carbondioxide

Show answer
Correct Option: A
Explanation:

Trapping of sun’s heat in the lower atmosphere due to increase in the pollution causing gases like carbon dioxide is called greenhouse effect.

Greenhouse gases are carbon dioxide, methane and ozone, nitrous oxide etc.

Sun’s radiation is partly absorbed by earth and rest of the radiations are reflected back to the atmosphere. But the greenhouse gases form blanket in the atmosphere and traps the radiation from escaping. This causes an increase in earth’s temperature resulting in Global warming.

In recent times man has turned his attention towards ___development by controlling environment pollution and conservation of nature.

Particulate matter is released in the air mainly from ___________.

geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

  1. Burning fossil fuels

  2. Dumping glass and garbage on land

  3. Hot water from factories

  4. Heavy metal effluents

Show answer
Correct Option: A
Explanation:

Fossil fuels include coal, petroleum, natural gas etc. These are used to generate energy for transportation cooking and many other. Such actions release particulate matter which includes suspended chemical compounds like oxides of sulphur and nitrogen and dangerous gases like carbonmonooxides.

The most serious environmental effect posed by hazardous wastes is :

geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

  1. contamination of groundwater.

  2. air pollution.

  3. increased use of land for landfills.

  4. none of the above.

Show answer
Correct Option: A
Explanation:

Ground water is one of the important sources for irrigation and drinking. Contamination of ground water by hazardous wastes causes serious environmental effect.

Ground water is often contaminated by man-made products such as gasoline, oil, road salts and chemicals get into the groundwater and cause it to become unsafe and unfit for human use

The increase in the concentration of CO2 in our environment in last fifty years; since 1960 is about :

geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

  1. 20%

  2. 14%

  3. 10%

  4. 6%

Show answer
Correct Option: B
Explanation:

CO2 is one of the major gases causing greenhouse effect. Increase in the concentration of CO2 in our environment in last fifty years since 1960 is about 14% which is a huge change. This is mostly anthropogenic that is manmade. Extensive industrialisation, urbanisation, increase in the vehicular transport, deforestation are attributed to this increase in carbon dioxide percentage

How the biological oxygen demand gets affected with the increased presence of organic matter in water?

geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

  1. the oxygen demand decrease

  2. the oxygen demand remains unchanged

  3. the oxygen demand increases

  4. All of the above

Show answer
Correct Option: C

Groundwater mining in coastal areas can result into :

geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

  1. increase in the salinity of groundwater.

  2. increase in the water table.

  3. decrease in the toxicity of groundwater.

  4. decrease in the salinity of groundwater.

Show answer
Correct Option: A
Explanation:

Ground water mining is the removal, or withdraw, of water from the natural source. Ground water is contained in specific rock units called aquifers.

Ground water mining in the coastal areas is very harmful because when the water is drawn sea water reverses its flow towards the water that is being used and causes an increase in salinity.


________ is the concentration of foreign matter in the air which adversely affects the well-being of human beings, animals, plants and their environment.

geography pollution - types and sources environmental risks of economic development tundra climatic region effects and successes of environment conservation

  1. Air pollution

  2. Water pollution

  3. soil pollution

  4. none of these
