In the application level, the atmospheric pressure is stated in kilo-pascals. Sorry – C02 is not the major greenhouse gas. Which of the following conditions is/are conducive for the formation of tropical cyclones? The atm unit is roughly equivalent to the mean sea-level atmospheric pressure on Earth, that is, the Earth's atmospheric pressure at sea level is approximately 1 atm. The temperature here is nearly constant, and hence, it is called tropopause. It is from asthenosphere that the molten rock materials find their way to the surface. Atmospheric pressure is around us all of the time. Its variation is the main cause of air motion/ wind. Carbon dioxide is largely responsible for the greenhouse effect. One millibar is defined as 1000 dynes per square centimeter (1 dyne is the force required to accelerate 1 gram of a mass 1 centimeter per second per second). Thanks for providing material free of cost . Gases are very sparse in this sphere due to the lack of gravitational force. In general, the atmospheric pressure decreases on an average at the rate of about 34 millibars every 300 metres of height. The exosphere is the uppermost layer of the atmosphere. During the condensation, water vapour gets condensed in the form of droplets around these dust particles and thus clouds are formed. Download ClearIAS Mock Exams apk 11 for Android. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere. Very Nice article. Troposphere contains dust particles and water vapour. The atmosphere is a mixture of different gases. The relative thickness of the ozone layer is measured in Dobson Units. 3. inflow of air at upper level of atmosphere. a. i … These variations are highly significant in terms of wind direction and speed. The portion of the gases changes in the higher layers of the atmosphere in such a way that oxygen will be almost negligible quantity at the heights of 120 km. Atmospheric pressure changes as the height or altitude increases. After this, the temperature increases slowly with the increase in the height. Thus, Coriolis force, Pressure Gradient Force, Ferrel s Law play a major role in determining the velocity and direction of a wind. It is measured with the help of a mercury barometer or the aneroid barometer. There are different types of movements of ocean water under the influence of different physical characteristics like temperature, salinity, density, etc. The zone separating troposphere from the stratosphere is known as tropopause. This rising volume of carbon dioxide is the main reason for global warming. 900mb. Use Special Code “AJITLIVE” to get 10% discount on your Unacademy Subscription.
