Composition of Air
Air is a mixture of various gases that surround the Earth. Understanding its composition is essential for comprehending how it supports life and various natural processes.
Main Components of Air
- Nitrogen (N2):
- Makes up about 78% of the Earth's atmosphere.
- Inert gas, plays a crucial role in maintaining the stability of the atmosphere.
- Oxygen (O2):
- Constitutes around 21% of the atmosphere.
- Essential for respiration in living organisms and combustion processes.
- Carbon Dioxide (CO2):
- Comprises approximately 0.04% of air.
- Important for photosynthesis in plants and regulating Earth’s temperature.
- Water Vapor (H2O):
- Varies from 0% to 4%, depending on temperature and humidity.
- Plays a vital role in weather patterns and climate.
Why Option 'C' is Correct
Option 'C' states that the composition of air includes Nitrogen, Oxygen, and Carbon Dioxide, which accurately reflects the primary components of Earth's atmosphere.
Why Other Options are Incorrect
- Option 'A': Oxygen and carbon dioxide only – ignores nitrogen, the dominant gas.
- Option 'B': Oxygen, nitrogen, and water vapor – excludes carbon dioxide, an essential component.
- Option 'D': Nitrogen and water vapor only – misses both oxygen and carbon dioxide, which are vital for life.
In summary, the correct answer is option 'C', as it includes all significant gases that make up the air we breathe. Understanding these components helps us appreciate the delicate balance that supports life on Earth.
