The cloud seeding and formation of clouds will be adversely affected. Which of the statements given above is/are correct? Correct Answer 1, 2, 3 and 4

The correct answer is 1, 2, 3 and 4.

Key Points

Acidification of Oceans-

  • Ocean Acidification refers to a decline in ocean PH due to excess absorption of carbon oxide.
  • An estimated 30-40% of the carbon dioxide from human activity released into the atmosphere dissolves into oceans, lakes and rivers.

Important Points

Impacts of Ocean Acidification-

  • The increase in the concentration of carbon dioxide led to an increase in carbonic acid and a decrease in carbonate ions.
  • The decrease in the number of carbonate ions available makes it more difficult for marine calcifying organisms, such as coral. Hence statement 2 is correct.
  • The growth and survival of calcareous phytoplankton will be adversely affected. Hence statement 1 is correct.
  • The survival of some animals that have phytoplanktonic larvae will be adversely affected. Hence statement 3 is correct.
  • The majority of atmosphere sulphur is emitted from the ocean in form of dimethylsulfide produced by phytoplankton.
  • But the increase in ocean acidification led to an adverse impact on the development of phytoplankton, which led to a low amount of sulphur emission.
    • This led to decreased cloud formation. Hence statement 4 is correct.
