Answer:
Solution:
Explain Question:
In this question some gases are given in list-I and we have to match them with their geometry and effect they cause to environment given in list-II.
Concept:
The greenhouse effect is the process by which certain gases in the Earth's atmosphere (like CO2, CH4, and water vapour) trap heat from the Sun. This keeps the Earth warm enough to support life. However, human activities like burning fossil fuels increase these gases, leading to global warming and climate change. Acid rain is rainwater that becomes acidic due to pollutants like sulfur dioxide (SO2) and nitrogen oxides (NOX) released from factories and vehicles. These gases react with water in the atmosphere to form acids, which fall to Earth as acidic precipitation, damaging plants, water bodies, soil, and buildings.
Solution:
The greenhouse effect is the process by which certain gases in Earth's atmosphere trap heat, preventing it from escaping into space, thereby warming the planet.
Key Greenhouse Gases:
Carbon dioxide (CO2)
Methane (CH4)
Nitrous oxide (N2O)
Water vapour (H2O)
Ozone (O3)
Acid rain refers to any form of precipitation (rain, snow, fog) that has a pH lower than normal (~5.6) due to the presence of strong acids like sulfuric acid (H2SO4) and nitric acid (HNO3). Causes:
Burning of fossil fuels (coal, oil, gas) releases:
Sulfur dixide (SO2)
Nitrgen oxides (NO, NO2)
Final Answer: (A)
