A Correct answer
Explanation

Though industrial development in India caused enormous improvement in India’s economy, it also proved disastrous to the environment.

Industries caused air pollution due to the smoke released from factories.

They also caused water pollution due to the draining of industrial wastes into water bodies causing hectic problems to marine and human life.

Main pollution is caused by chemical industries.

A Correct answer
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.

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

  1. 20%

  2. 14%

  3. 10%

  4. 6%
Reveal answer Fill a bubble to check yourself
B Correct answer
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?

  1. the oxygen demand decrease

  2. the oxygen demand remains unchanged

  3. the oxygen demand increases

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

Biological oxygen demand (BOD) measures the amount of dissolved oxygen required by aerobic microorganisms to decompose organic matter. When more organic matter is present, more oxygen is consumed by these organisms, leading to an increase in BOD.

Groundwater mining in coastal areas can result into :

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