The layer that surrounds the earth and protects us from harmful radiations of the sun is called the Atmosphere.
The atmosphere is a blanket-like layer of gases that surrounds the earth. It plays a crucial role in supporting life on our planet. Here are some key points about the atmosphere:
1. Importance:
- The atmosphere contains essential gases like oxygen, which is necessary for most organisms to breathe and carry out their life processes.
- It also acts as a protective shield against harmful ultraviolet (UV) radiation from the sun, preventing it from reaching the earth's surface in excessive amounts.
2. Composition:
- The atmosphere is comprised of a mixture of gases, primarily nitrogen (78%) and oxygen (21%), with trace amounts of other gases like carbon dioxide, water vapor, and noble gases.
- These gases are distributed in different layers based on their composition and properties.
3. Layers:
- The atmosphere is divided into several layers, including the troposphere, stratosphere, mesosphere, thermosphere, and exosphere.
- Each layer has different characteristics and plays a unique role in the functioning of the atmosphere.
4. Functions:
- The atmosphere helps regulate the earth's temperature by trapping heat and preventing it from escaping into space, a phenomenon known as the greenhouse effect.
- It also helps distribute heat around the planet through processes like convection and conduction, contributing to weather patterns and climate.
5. Protection:
- The atmosphere acts as a shield against harmful ultraviolet (UV) radiation from the sun. The ozone layer, located in the stratosphere, absorbs much of the sun's UV radiation, protecting life on earth from its harmful effects.
In conclusion, the layer that surrounds the earth and protects us from harmful radiations of the sun is called the atmosphere. It is a crucial component for supporting life on our planet and plays a vital role in regulating temperature and protecting us from harmful radiation.
