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.

What are some functions of the atmosphere?

The atmosphere serves several critical functions, including providing essential gases like oxygen for respiration and carbon dioxide for photosynthesis. It acts as a protective shield, absorbing harmful solar radiation and reducing temperature extremes between day and night. Additionally, the atmosphere plays a vital role in weather and climate regulation, facilitating the water cycle and distributing heat around the planet. Lastly, it enables sound propagation and supports various life forms by maintaining suitable pressure and temperature conditions.


Why it is cold at night at moon and hot at day?

The Moon has no protective atmosphere, as Earth does. On Earth, the atmosphere absorbs part of the heat, and moves it around.


How was the early atmosphere different from your atmosphere?

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.


What are the 2 main functions of any atmosphere?

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.


What is the protective layer of the atmosphere destroyed by CFC's?

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.
