Which layer protect us from the scorching heat of the suna)Atmosphereb)Biospherec)Hydrosphered)LithosphereCorrect answer is option 'A'. Can you explain this answer?

Question

Answer

Because atmosphere contains a layer called Ozone.
This layer don't allow Ultraviolet rays to enter inside Atmosphere.

Answer

_it is blanket of air which surrounds our planet. it is held to surface of the Earth by the gravitational force. The atmosphere contains approximately 78.03% of nitrogen ,20.99% of oxygen, 0.98% of carbon dioxide and other gases_

Answer

Introduction
The layer of the Earth's atmosphere known as the ozone layer is primarily responsible for protecting us from the scorching heat of the sun. This layer plays a crucial role in shielding the Earth's surface from harmful ultraviolet (UV) radiation emitted by the sun.

The Atmosphere
The atmosphere is a layer of gases that surrounds the Earth and is divided into several layers based on temperature variations. The ozone layer is located within the stratosphere, which is the second layer of the atmosphere.

The Ozone Layer
The ozone layer is a region within the stratosphere that contains a high concentration of ozone (O3) molecules. Ozone is a molecule composed of three oxygen atoms and is highly effective in absorbing and scattering UV radiation from the sun.

Protection from UV Radiation
UV radiation is classified into three types: UVA, UVB, and UVC. UVA radiation has the longest wavelengths and is the least harmful, while UVC radiation has the shortest wavelengths and is the most dangerous. UVB radiation, with intermediate wavelengths, is the primary concern as it can cause sunburn, skin damage, and an increased risk of skin cancer.

The ozone layer acts as a shield, absorbing the majority of the sun's UVB radiation. Ozone molecules in the stratosphere absorb UVB rays, converting their energy into heat. This absorption prevents a significant amount of harmful radiation from reaching the Earth's surface, reducing the risk of skin damage and other negative effects.

Importance of the Ozone Layer
The ozone layer is crucial for maintaining life on Earth. Without this protective layer, the intense UVB radiation would reach the surface, causing severe harm to both human beings and the environment.

The ozone layer also plays a role in regulating the Earth's temperature. It acts as a greenhouse gas, trapping heat within the atmosphere and preventing it from escaping into space. This helps maintain a stable climate and prevents extreme temperature fluctuations.

Conclusion
The atmosphere, specifically the ozone layer within the stratosphere, is responsible for protecting us from the scorching heat of the sun. The ozone layer absorbs and scatters UVB radiation, reducing its harmful effects on the Earth's surface. Understanding the importance of the ozone layer is crucial for preserving our well-being and the health of our planet.
