Gas which protect us from harmful UV rays

There are several gases in the Earth's atmosphere that play a crucial role in protecting us from harmful UV rays. Among these gases, ozone is the primary gas responsible for filtering out the majority of UV radiation. Let's explore in detail how ozone and other gases protect us from these harmful rays.

1. Ozone:
Ozone is a molecule composed of three oxygen atoms (O3). It is mainly found in the stratosphere, a layer of the atmosphere located approximately 10 to 50 kilometers above the Earth's surface. Ozone acts as a protective shield by absorbing the majority of the Sun's ultraviolet-B (UV-B) and ultraviolet-C (UV-C) radiation. UV-B and UV-C rays can be harmful to living organisms, causing skin cancer, cataracts, and other health issues.

2. Nitrogen:
While nitrogen (N2) is the most abundant gas in the Earth's atmosphere, it does not directly protect us from UV rays. Nitrogen is mainly involved in other atmospheric processes and does not have significant UV absorption properties.

3. Oxygen:
Oxygen (O2) is another crucial component of the Earth's atmosphere, but it also does not provide significant protection against UV radiation. Oxygen primarily plays a vital role in respiration and supporting life on Earth.

4. Carbon Dioxide (CO2):
Carbon dioxide (CO2) is a greenhouse gas that absorbs and emits infrared radiation, contributing to global warming. However, it does not have a direct impact on protecting us from UV rays.

Conclusion:
In summary, the gas that primarily protects us from harmful UV rays is ozone. Ozone, found in the stratosphere, acts as a protective shield by absorbing the majority of UV-B and UV-C radiation from the Sun. While other gases like nitrogen, oxygen, and carbon dioxide have their own roles in the atmosphere, they do not provide significant protection against UV radiation. It is essential to preserve and protect the ozone layer to maintain its shielding effect and minimize the harmful effects of UV rays on our health and the environment.

It is ozone layer . Ozone layer protects us from the harmful UV rays of sun. That's why Ozone layer is very important for us if it will get finish so we may burn,have cancer,blindness and sun burn etc. So, therefore, the result will be very harmful.

The Ozone layer is present in stratosphere. It is one of a layer of air .
