In fact, the temperature reversal starts from the stratopause, i. There are various factors responsible for heating of Layers of the atmosphere essay earth. Above it a fall in temperature is recorded. Thus, warmer air becomes lighter and rises upward and a vertical circulation of air is set in.
This region is called the ionosphere. When two bodies with unequal temperature come into contact, there is a flow of energy from the warmer body to the cooler one. Convection is the main process in the heating of the atmosphere. The only clouds found in the stratosphere are very thin wispy clouds formed of tiny ice crystals.
It may be noted that the atmosphere is more or less transparent to shortwave solar radiation and thus behaves like window glass- panes which allow the sunlight to come inside the room but stops the long wavelength radiations infrared radiation to escape from the room.
Heating of the Atmosphere by Direct Insolation: All the layers of the atmosphere are of interest to the ecologists since together they form the total blanket of air in the biosphere.
The changes that are occurring now have their origin in the Industrial Revolution since and the expansion of technology. The lower layer of atmosphere especially that comes into direct contact with the surface of the earth gets heated through the process of conduction.
All the living organisms depend upon this layer for their survival. The height of tropopause varies with latitude. Transfer of heat of atmosphere from one place to another is known as convection. The upper strata is rich in ozone.
Water vapour and carbon dioxide in the troposphere trap some of this heat, preventing it from escaping thus keep the Earth warm. Moreover, because of its extra heat ozonosphere also acts like a blanket that reduces the cooling rate of the earth and thus adds to the effect of water vapour.
It is obvious that heat moves from warmer body to the cooler body through molecular movement. These changes are directly related to human events and activities.
Radiation from the earth is called terrestrial radiation. In the thermosphere molecules of air are so widely spaced that high frequency audible sounds are not carried by the atmosphere. At the very top of the troposphere is the tropopause where the temperature reaches a stable minimum.
It contains only atoms, like hydrogen, helium etc.Essay on Amazing Atmosphere of the Earth Words | 3 Pages. The Earth’s atmosphere is divided up into the Troposphere, Stratosphere, Mesosphere and the Thermosphere.
The Earth’s ozone layer is located in the lower stratosphere, which begins about 6 to 10 miles above the Earth’s surface and expands up to about 30 miles.
Read this essay to learn about Atmosphere, Composition of Atmosphere and Energy Balance in Atmosphere! Atmosphere: Atmosphere is a multi-layered envelope of different gases (just like a protective blanket) surrounding the earth which holds up life on earth and saves it from harmful environment of outer space.

These include the troposphere, the stratosphere, the mesosphere, the heterosphere and the exosphere (Fig.
81), each of which has following physico-. Essay on Amazing Atmosphere of the Earth Words 3 Pages The Earth’s atmosphere is divided up into the Troposphere, Stratosphere, Mesosphere and the Thermosphere.
The atmosphere is divided into four layers. The atmosphere also has a layer of ozone. The layers of the atmosphere listed from lowest altitude to highest altitude are the troposphere, stratosphere, mesosphere and thermosphere.Download
