Due to their extensive rice cultivation, some regions may be contributing to global warming. To what possible reason/reasons is this attributable?
1.The anaerobic conditions associated with rice cultivation cause the emission of methane.
2.When nitrogen based fertilizers are used, nitrous oxide is emitted from the cultivated soil.
Which of the statements given above is/are correct?
Both 1 and 2
Correct AnswerNeither 1 nor 2
Incorrect AnswerExplanation:
Both 1 and 2
The first statement is correct. Anaerobic conditions, which are common in waterlogged rice fields, facilitate the production and release of methane (CH4), a potent greenhouse gas. Rice paddies are a significant source of methane emissions globally.
The second statement is also correct. The use of nitrogen-based fertilizers in rice cultivation can lead to the emission of nitrous oxide (N2O) from the soil. Nitrous oxide is another powerful greenhouse gas, and its emission is a concern in agricultural practices that rely heavily on nitrogen fertilizers.
Therefore, both statements are correct and contribute to explaining how rice cultivation can impact global warming.
