Question

question 28
which is the dominant greenhouse gas leading to global warming of the atmosphere?
○ h₂o
○ co₂
○ no₂
○ ch₄

Explanation:

Greenhouse gases trap heat in the atmosphere. While water vapor (\(H_2O\)) is a greenhouse gas, its concentration is largely determined by temperature. Nitrogen dioxide (\(NO_2\)) is not a major greenhouse gas. Methane (\(CH_4\)) is a potent greenhouse gas but its concentration is much lower compared to carbon dioxide (\(CO_2\)). Carbon dioxide (\(CO_2\)) is released in large quantities from human activities like burning fossil fuels and deforestation. It has a long - term impact on the atmosphere and is the dominant greenhouse gas contributing to global warming.

Answer:

\(CO_2\)
