The Earth's atmosphere is a mixture of gases, suspended particles, and water vapor that surrounds the planet. The composition of the atmosphere can be divided into major gases, trace gases, and variable components. Here are the primary components of the Earth's atmosphere: 1. Nitrogen (N2): Nitrogen is the most abundant gas in the atmosphere, accounting for about 78% of the total volume. It is a crucial element for living organisms and plays a role in various chemical processes. 2. Oxygen (O2): Oxygen makes up approximately 21% of the atmosphere. It is essential for respiration, supporting the survival of aerobic organisms. 3. Argon (Ar): Argon is an inert gas and makes up around 0.93% of the atmosphere. It is obtained from the decay of radioactive potassium in the Earth's crust. 4. Carbon Dioxide (CO2): Carbon dioxide is a trace gas, but its concentration has been increasing due to human activities, primarily the burning of fossil fuels and deforestation. It currently make...
