Many people today assume mistakenly that the Earth is so big that we humans cannot possibly have any major impact on the way our planet's ecological system operates.
Oxygen makes up 21% of the Earths atmosphere.
The gas that makes up 93% of Earth's atmosphere is nitrogen. Oxygen is the second most abundant gas, making up around 21%.
Approximately 100 tons of meteors enter Earth's atmosphere every day. Most of these meteors are small and burn up upon entry, creating shooting stars.
When solar radiation enters the atmosphere, most of it is absorbed by the Earth's surface. However, about 6 percent of the solar radiation is reflected back into space by the Earth's surface. This reflection occurs mainly from surfaces like ice, snow, and water, which have high albedo, meaning they reflect a significant portion of incoming solar energy.

Nitrogen makes up most of our atmosphere. Second is Oxygen.
Most kinds of weather occurs in the troposphere, the lowest level of the atmosphere.
Nitrogen has made up the largest portion of Earth's atmosphere for most of Earth's history. It currently makes up about 78% of the atmosphere.
