Explanation
The highest percentage in the atmosphere is of nitrogen, which makes up approximately 78% of the Earth's atmosphere.
Oxygen, which is necessary for respiration and is essential for life, makes up about 21% of the Earth's atmosphere. Carbon dioxide, a greenhouse gas that plays a crucial role in regulating the Earth's temperature, makes up only about 0.04% of the atmosphere. Helium, an inert gas, makes up less than 0.0005% of the Earth's atmosphere.
Here are the approximate percentages of these gases in the Earth's atmosphere:
Nitrogen: 78.08%
Oxygen: 20.95%
Argon: 0.93%
Carbon dioxide: 0.04%
Neon: 0.0018%
Helium: 0.0005%
Methane: 0.0002%
Krypton: 0.0001%
Hydrogen: 0.00005%
It's important to note that these percentages can vary slightly depending on factors such as altitude, location, and weather conditions.
