write briefly about layers of the atmosphere
Answers
Answer:
Historically, the terms "Gurkha" and "Gorkhali" were synonymous with "Nepali", which originates from the hill principality Gorkha Kingdom, from which the Kingdom of Nepal expanded under Prithivi Narayan Shah. The name may be traced to the medieval Hindu warrior-saint Guru Gorakhnath who has a historic shrine in Gorkha.
Explanation:
The atmosphere can be divided into layers based on its temperature, as shown in the figure below. These layers are the troposphere, the stratosphere, the mesosphere and the thermosphere. A further region, beginning about 500 km above the Earth's surface, is called the exosphere.
Different layers of the atmosphere are:-
Troposphere - It is the layer just above the earth’s surface whose distance is between 0 - 10km. It contains most of the air and oxygen which is essential for all living organisms. This air is used for respiration and other functions for the survival of human beings. It also forms the weather conditions of the earth.
Stratosphere - The layer above the troposphere at a distance between 10 - 50km above the earth’s surface. It consists of the ozone layer which protects the earth from ultraviolet rays of the sun.
Mesosphere - The layer above stratosphere at a distance between 50 - 80km above the earth’s surface. This layer is very cold and burns most of the meteors preventing them from reaching the earth’s surface.
Thermosphere - The layer above the mesosphere at a distance between 80 - 320km above the earth’s surface.
