Earth’s atmosphere is 78% Nitrogen and 21% oxygen by volume, the remaining 1% includes gases like argon, carbon dioxide, etc.
The atmosphere becomes less dense as the altitude increases.
The Karman line is the boundary between outer space and Earth’s atmosphere. Karman line is 100 km above sea level.
Because a single atom of chlorine can destroy hundreds of thousands of ozone molecules, the usage of chlorofluorocarbon is restricted.
When the solar wind from the sun strikes the upper atmosphere of Earth, a beautiful light, called aurora, can be seen in the northern and southern poles.
Troposphere, stratosphere, mesosphere, thermosphere, and exosphere are the five layers of Earth’s atmosphere.
The majority of the molecules in the air are in Troposphere (first layer above the surface)
Humans and animals are protected from dangerous UV radiation by the ozone layer, which is 20-30 kilometers above the Earth's surface.
Sometimes sulfur dioxide and nitrogen dioxide combine with water molecules in the atmosphere to form acid rain. Acid rains are harmful to all living creatures on Earth.
The temperature in the thermosphere layer of the atmosphere can reach 2,000 degrees Celsius (or 3632 degrees Fahrenheit).
