SOLAR SYSTEM

Detailed explanation-1: -Carbon dioxide is released into the atmosphere by cell respiration in living organisms and also by combustion of biomass and fossil fuels. (It is removed from the atmosphere by photosynthesis and by dissolving in the oceans.) Water vapour is formed by evaporation from the oceans and also transpiration in plants.

Detailed explanation-2: -Answer and Explanation: The answer is c. photosynthesis.

Detailed explanation-3: -It works like this: As greenhouse gases like carbon dioxide and methane increase, Earth’s temperature rises in response. This increases evaporation from both water and land areas. Because warmer air holds more moisture, its concentration of water vapor increases.

Detailed explanation-4: -Greenhouse gases include carbon dioxide, methane, nitrous oxides, and water vapor. (Water vapor, which responds physically or chemically to changes in temperature, is called a “feedback.") Scientists have determined that carbon dioxide’s warming effect helps stabilize Earth’s atmosphere.
