No one gas comprises 99% of the atmosphere, but nitrogen (~78.09%) and oxygen (~20.95%) together comprise about 99% of the atmosphere (on a dry basis, i.e. not including water vapor which can range from near 0% to 5%).

Salt water (in the form of oceans, seas and straits).
They look at the mineral composition of the rocks. There are some minerals that can only form in the presence of oxygen.
what causes changes to earths landform
The formation of Earth's early atmosphere was primarily influenced by volcanic outgassing, which released gases such as water vapor, carbon dioxide, nitrogen, and methane. As the planet cooled, water vapor condensed to form oceans, while volcanic activity continued to release gases into the atmosphere. Additionally, impacts from comets and asteroids may have contributed volatile compounds, further shaping the atmospheric composition. Over time, these processes laid the foundation for the development of a more stable atmosphere and the emergence of life.
As you go higher in the atmosphere the gases start to compose or join together which causes them to change since there is mixture of more than one gas. Sometimes they form a different element when certain gases form.

By the earths atmosphere
Microwave rays can pass through the Earth's atmosphere, as they are a form of electromagnetic radiation that is not absorbed or blocked by gases in the atmosphere. This is why microwave communication systems like satellites are able to transmit signals through the atmosphere.

In the atmosphere, in the form of carbon dioxide
The mixture of gases in the atmosphere is not considered a solution, suspension, or colloid because gases are uniformly distributed and do not form distinct phases in the atmosphere. It is more accurately described as a homogeneous mixture of gases known as air.

The Earth's protective shield is primarily formed by gases like oxygen (O2) and ozone (O3) in the atmosphere. These gases help absorb and block harmful ultraviolet radiation from the sun, protecting life on Earth from its damaging effects. Additionally, nitrogen (N2) in the atmosphere helps maintain a stable balance of gases that contribute to Earth's protective shield.
Acid deposition, commonly known as acid rain, occurs when gases like sulfur dioxide and nitrogen oxides react with water vapor in the atmosphere to form sulfuric and nitric acids. These acids then fall back to Earth's surface in the form of precipitation, causing harm to ecosystems, infrastructure, and human health.
Earth's atmosphere formed around 4.5 billion years ago, shortly after the planet's formation. The early atmosphere likely consisted of gases such as hydrogen and helium, but has since evolved through volcanic activity and the presence of living organisms to the composition we see today.
