Answer 2

AnswEarth's Atmosphere

The atmosphere is a mixture of nitrogen (78%), oxygen (21%), and other gases (1%) that surrounds Earth. High above the planet, the atmosphere becomes thinner until it gradually reaches space. It is divided into five layers. Most of the weather and clouds are found in the first layer.

The atmosphere is an important part of what makes Earth livable. It blocks some of the Sun's dangerous rays from reaching Earth. It traps heat, making Earth a comfortable temperature. And the oxygen within our atmosphere is essential for life.

Over the past century, greenhouse gases and other air pollutants released into the atmosphere have been causing big changes like global warming, ozone holes, and acid rain.

How did life evolve on Earth during the Archean, when the Sun was about 25% weaker than today? The Earth should have been glaciated, if greenhouse gas concentration was the same as today. Researchers studying the isotopic signatures of Earth's early atmosphere in rocks from Northern Australia have ruled out high levels of nitrogen as a possible way to increase warming from atmospheric carbon dioxide.n:
