Which of the following gases absorbs ultra violet rays?a)Carbon Dioxideb)Neonc)Ozoned)NitrogenCorrect answer is option 'C'. Can you explain this answer?

Question

Answer

Ozone splits In to oxygen molecule and oxygen free radical. which is readily recombinable. Thus it's make cyclic process in presence of ultraviolet rays.

Answer

Ozone is the combination of three oxygen atoms into a single molecule (O3). It is a gas produced naturally in the stratosphere where it strongly absorbs incoming UV radiation. But as stratospheric ozone decreases, UV radiation is allowed to pass through, and exposure at the Earth's surface increases. I hope you got your answer.

Answer

Ozone is the gas that absorbs ultraviolet (UV) rays. It is a molecule made up of three oxygen atoms (O3) and is present in the Earth's atmosphere. Ozone is primarily found in the stratosphere, a layer of the atmosphere located approximately 10 to 50 kilometers above the Earth's surface.

Ozone layer formation:
The formation of ozone occurs when oxygen molecules (O2) in the stratosphere are split apart by UV-C radiation from the sun. These oxygen atoms (O) then combine with other oxygen molecules to form ozone (O3). This process is known as the ozone-oxygen cycle and is responsible for the creation and maintenance of the ozone layer.

Ozone's ability to absorb UV rays:
Ozone molecules have the unique ability to absorb UV rays, particularly those in the UV-B and UV-C range. UV-B rays have wavelengths between 280 and 315 nanometers, while UV-C rays have wavelengths below 280 nanometers. These types of UV rays are harmful to living organisms, as they can cause skin cancer, cataracts, and damage to marine ecosystems.

The absorption of UV rays by ozone occurs due to the presence of a specific bond between the oxygen atoms in the molecule. This bond is known as the ozone-oxygen bond and is highly reactive to UV radiation. When UV rays encounter ozone molecules, they are absorbed and converted into heat energy. This process prevents most of the UV rays from reaching the Earth's surface and provides protection for life on Earth.

Importance of the ozone layer:
The ozone layer plays a crucial role in protecting the Earth's surface from harmful UV radiation. Without this layer, life as we know it would not be possible. Increased exposure to UV rays can lead to a variety of health issues, including skin cancer, weakened immune systems, and damage to plant and animal life.

Human activities and the ozone layer:
Unfortunately, human activities have led to the depletion of the ozone layer, primarily through the release of chlorofluorocarbons (CFCs) and other ozone-depleting substances (ODS). These substances were commonly used in refrigeration, air conditioning, aerosol propellants, and foam-blowing agents. When released into the atmosphere, they break down ozone molecules, reducing the overall ozone concentration in the stratosphere.

In conclusion, ozone is the gas that absorbs UV rays. It forms a protective layer in the Earth's atmosphere, known as the ozone layer, which helps shield the planet from harmful UV radiation. However, human activities have caused ozone depletion, emphasizing the need for international efforts to reduce the use of ozone-depleting substances and protect the ozone layer.
