The atmosphere serves several protective functions, including filtering harmful solar radiation, particularly ultraviolet rays, thus shielding living organisms from damage. It also regulates temperature by trapping heat through the greenhouse effect, maintaining a stable climate conducive to life. Additionally, the atmosphere protects the Earth from space debris by burning up smaller meteoroids upon entry, preventing them from reaching the surface. Lastly, it plays a critical role in weather patterns, which helps sustain ecosystems and biodiversity.
The Moon has no protective atmosphere, as Earth does. On Earth, the atmosphere absorbs part of the heat, and moves it around.
The early Earth's atmosphere was likely composed of gases like carbon dioxide, water vapor, nitrogen, and minimal oxygen. It was lacking in oxygen compared to the current atmosphere, which is about 21% oxygen. Additionally, early Earth's atmosphere lacked the protective ozone layer present in our atmosphere today.
The two main functions of any atmosphere are to provide essential gases for life, such as oxygen for respiration and carbon dioxide for photosynthesis, and to protect the planet's surface from harmful solar and cosmic radiation. Additionally, the atmosphere helps regulate temperature through the greenhouse effect, maintaining a stable climate that supports various ecosystems.
The protective layer of the atmosphere that is destroyed by CFCs is the ozone layer. CFCs (chlorofluorocarbons) break down ozone molecules, leading to ozone depletion. This thinning of the ozone layer allows more harmful ultraviolet (UV) radiation from the sun to reach the Earth's surface, posing risks to human health and the environment.
Mars has a very thin atmosphere composed mainly of carbon dioxide with traces of nitrogen and argon. It lacks a protective ozone layer, and the atmospheric pressure is about 1% of Earth's. The thin atmosphere contributes to the planet's cold temperatures and makes it unable to support liquid water on its surface.

The protective ozone layer is a part of the atmosphere. It is a pool of ozone molecules.

Venus is a planet that has a smooth unmarked surface caused by a thick protective atmosphere. The atmosphere of Venus is mostly carbon dioxide, which is surrounded by sulfuric acid clouds.
Earth has a protective bnaket of ozone layer. It is present in stratosphere.
