Facts about air:

Composition: 

Air is a mixture of gases: 78% nitrogen and 21% oxygen, with some traces of argon, carbon dioxide, neon, and hydrogen.

Aerosols: 

In addition to gases, air contains tiny particles called aerosols, such as dust, pollen, soot, and smoke, which contribute greatly to air pollution.

Essential for Life: 

Air is needed and vital for respiration, a process where living things take in oxygen and release carbon dioxide, providing us with energy to eat, grow, and live.

Carbon Dioxide: 

This gas is crucial for photosynthesis, during which plants produce food and oxygen; however, high levels resulting from the burning of fossil fuels contribute to global warming.

Humidity: 

Relative humidity measures the amount of water air can hold before it rains, with 100% humidity indicating rain is imminent.

Air Pressure: 

The weight of air creates atmospheric pressure, which is higher at sea level and lower at high altitudes. This pressure affects our ears during elevation changes.

Protective Layer: 

Earth’s atmosphere, which is filled with air, acts as insulation to maintain temperature and contains ozone, which shields us from too much sunlight.

Meteoroid Shield: 

The air in our atmosphere protects us by causing meteoroids to burn up before reaching the Earth’s surface.

Microbial Life: 

The air hosts bioaerosols, tiny microbial organisms that can travel long distances through wind, rain, or sneeze.

Air Quality Index (AQI): 

AQI measures air pollution levels, with values over 300 representing hazardous conditions.

Next week, we will be grateful for things that start with the letter B.
