Evaporation takes place in the oceans, seas, rivers, ponds and lakes while transpiration takes place from the plants, trees and living beings. It decreases at the rate of 1 degree Celsius for every 165 m of height. Pressure Gradient Force is created due to the difference in the atmospheric pressure, and it is directed from the high pressure to the low pressure. One atmosphere is 1,013 millibar s, … We write simple, easy to understand articles, but always ensure high standards of quality. The air temperature at the tropopause is about – 80 degree Celsius over the equator and about – 45 degree Celsius over the poles. Take UPSC Civil Services Exam Prelims Mock Tests. Air pressure is measured with the help of a mercury barometer or the aneroid barometer. The rate of change of pressure with respect to distance is the pressure gradient. CO2 is not causing global warming! Required fields are marked *, "Working 24*7 in the police for the last 5 years and been out of touch with the preparation, I took the guidance from your website, especially the ClearIAS prelims test series. These dust particles help in the condensation of water vapour. Atmospheric pressure at sea level is about 101,000 Pa (101 kPa) but just 27,000 Pa (27 kPa) at the cruising altitude of a passenger plane. Plz provide all material in sequence manner. Based on the geographical location, the Cyclones are of two types namely Tropical Cyclones and Temperate Cyclones (Extra Tropical Cyclones). It contains life-giving gases like Oxygen for humans and animals and carbon dioxide for plants. The primary greenhouse ‘gas’ is water vapour in clouds. Water vapour reaches in the atmosphere through evaporation and transpiration. form the remaining part of the atmosphere. The temperature remains almost the same in the lower part of this layer up to the height of 20 km. At sea level, the average atmospheric pressure is 1 atm or 1,013.2 mb or 1,013.2 h Pa (kilo Pascal). 2) Consider the following statements and identify the right ones. Pressure Gradient Force – The differences in atmospheric pressure produces a force. Koppen Climate Classification System. After this, the temperature increases slowly with the increase in the height. The air is a mixture of several gases and it encompasses the earth from all sides. The vertical pressure gradient force is much larger than that of the horizontal pressure gradient. There are different types of movements of ocean water under the influence of different physical characteristics like temperature, salinity, density, etc. It is expressed in ‘milibar’ or mb unit. Pr … The air surrounding the earth is called the atmosphere. Due to gravitythe air at the surface is denser and hence has higher pressure. The atmosphere is a mixture of different gases. Composition and Structure of the Earth’s Atmosphere. Atmospheric pressure. Sorry – C02 is not the major greenhouse gas. The air is one among the necessary conditions for the existence of life on this planet. They are: What’s next in the series: Insolation and Heat Balance of the Earth. This is an important topic to study for candidates, as this is a part of the UPSC geography syllabus. We write simple, easy to understand articles, but always ensure high standards of quality. It contains a high concentration of ozone (O3) in relation to other parts of the atmosphere. However, 99 % of the total mass of the atmosphere is confined to the height of 32 km from the earth’s surface. a) 1 and 2 only The zone separating troposphere from the stratosphere is known as tropopause. Its variation is the main cause of air motion/ wind. Your material is excellent, I am your regular user. We all know that earth is a unique planet due to the presence of life. It acts as a filter and absorbs the ultra-violet rays radiating from the sun and prevents them from reaching the surface of the earth. It is measured in force per unit area. Hi Nikhil, thank you for the feedback and great to know that readers like you value our content so much. Therefore, at a place, if the air is dense for instance near the Earth’s surface (due to Gravity), the atmospheric pressure will be more. 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. Dust particles are generally found in the lower layers of the atmosphere. An atmosphere (atm) is a unit of measurement equal to the average air pressure at sea level at a temperature of 15 degrees Celsius (59 degrees Fahrenheit). The pressure varies from region to region. Yes, I want ClearIAS to help me score high! It envel… Wladimir Köppen (1846– 1940; pronounced like “kur-pin” with a silent r) was a Russian-born German climatologist who was also an amateur botanist..

It is measured with the help of a mercury barometer or the aneroid barometer. Though the direction and speed depend also on Frictional force and Coriolis force. The atmosphere is made up of different gases, water vapour and dust particles. We hope you would find this helpful. The exosphere is the uppermost layer of the atmosphere. Higher concentration of dust particles is found in subtropical and temperate regions due to dry winds in comparison to equatorial and polar regions. The amount of ozone gas in the atmosphere is very little and is limited to the ozone layer found in the stratosphere. Thanks for providing material free of cost . This layer is located between 80 and 400 km above the mesopause. (See Major Ocean Currents: How to learn faster?) It contains electrically charged particles known as ions, and hence, it is known as the. The standard atmosphere (symbol: atm) is a unit of pressure defined as 101,325 Pa (1,013.25 hPa; 1,013.25 mbar), which is equivalent to 760 mm Hg, 29.9212 inches Hg, or 14.696 psi. A volcano is a place where gases, ashes and/ or molten rock material ‘ lava’ escape to the ground through fissures and faults, etc. It is the source of all kinds of precipitation. In this layer, the temperature starts decreasing with increasing altitude and reaches up to – 100 degree Celsius at the height of 80 km. It contains life-giving gases like Oxygen for humans and animals and carbon dioxide for plants. For cracking the IAS. The atmosphere can be divided into five layers according to the diversity of temperature and density. The atmosphere is essential for the survival of plant and animal life. They also require the optimum temperature to keep themselves warm and grow. These notes will also be useful for other competitive exams like banking PO, SSC, state civil services exams, and so on. Atmospheric pressure is the weight of a column of air contained in a unit area from the mean sea level to the top of the atmosphere. The atmosphere is a mixture of different types of gases. Vertically, atmospheric pressure is highest at sea level, it is about 1013.2 Mb, atmospheric pressure gets decreases with altitude. Major Ocean Currents: How to learn faster? The air is one among the necessary conditions for the existence of life on this planet. The horizontal variation of the Pressure depends on the differential heating (insolation) of the surface which causes the differential air volumes. Atmospheric pressure is around us all of the time. 2. Atmospheric air mainly consists of – Nitrogen→ 78.03 %; Oxygen→ 20.99 %; Argon→.94 %; CO2→.03 %; H→.01 %; The rest are Neon, Helium, Ozone, The xenon & The krypton in very percentage of minute; Nitrogen. Sir,can we get topics separately or objective types…. i) Air pressure decreases when air descends. - Poonam Dalal, ClearIAS Online Student. The average decrease is about 1 mb per each 10m increase in elevation, subject to other factors such as Temperature, local topography, closeness to the sea, etc. Generally, atmosphere extends up to about 1600 km from the earth’s surface. You all know that the ocean water is never still. CO2 is a poor greenhouse gas. It also decreases from the equator (or from the low latitudes) towards the poles (or towards the high latitudes). 3. The pressure gradient is strong where the isobars are close to each other and is weak where the isobars are apart. Gases form of water present in the atmosphere is called water vapour. The pressure decreases with height. The thickness of the troposphere is greatest at the equator because heat us transported to great heights by strong convectional currents. 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). The winds in the upper atmosphere, 2 – 3 km above the surface, are free from frictional effect of the surface and are controlled by the pressure gradient and the Coriolis force. It envelops the earth all round and is held in place by the gravity of the earth. Ajit Tiwari and more top educators are teaching live on Unacademy. Sir thanks for providing material in sequence this was the only one thing which was not good in your material.

Horizontal distribution of pressure is studied by drawing isobars (lines connecting places having equal pressure) at constant levels. Atmospheric pressure is the weight of a column of air contained in a unit area from the mean sea level to the top of the atmosphere. Thus, Coriolis force, Pressure Gradient Force, Ferrel s Law play a major role in determining the velocity and direction of a wind. But, it is generally balanced by … Weather related incidents do not take place in this layer. In this article, we are going to discuss in details about some of the topics like insolation, terrestrial radiation, heat budget of the earth, albedo, etc. Your email address will not be published. This rising volume of carbon dioxide is the main reason for global warming. Nitrogen and oxygen are the two main gases in the atmosphere and 99 percentage of the atmosphere is made up of these two gases. Atmospheric pressure reduces with altitude for two reasons, both of which are related to gravity. The air surrounding the earth is called the atmosphere. Other gases like argon, carbon dioxide, neon, helium, hydrogen, etc. 8) Having covered most of the important concepts in Lithosphere and Hydrosphere, in this article, we are going to discuss the composition and structure of the Earth’s Atmosphere in detail. One important feature of stratosphere is that it contains a layer of ozone gas. It thus acts like a blanket allowing the earth neither to become too cold nor too hot. The temperature increases due to the presence of ozone gas in the upper part of this layer. General Circulation of the atmosphere is one of many concepts for UPSC Geography that candidates must familiarize themselves with. Composition and Structure of the Earth’s Atmosphere. These variations are highly significant in terms of wind direction and speed. When the volume of other gases remains constant in the atmosphere, the volume of the carbon dioxide has been rising in the past few decades mainly because of the burning of fossil fuels. 1B, Second Floor,Pusa Road, Karol Bagh, New Delhi - 110005 (Beside Karol Bagh Metro Station Gate No. The atmosphere is a mixture of different gases. The composition of the atmosphere is not static and it changes according to the time and place. The pressure decreases with height because air gets thinner. Its main feature is its zonal character known as pressure belts. The weight of a column of air contained in a unit area from the mean sea level to the top of the atmosphere is called the atmospheric pressure. It is from asthenosphere that the molten rock materials find their way to the surface. 1. large and continuous supply of warm and moist air. The air blows horizontally here. 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. Atmosphere is the air surrounding the earth. Therefore this layer is considered ideal for flying of aircraft.   TROPICAL CYCLONES Tropical Cyclones are violent storms that originate over the seas in the Low pressure belt of the tropical areas and move … This variation of the Atmospheric Pressure has been playing a very important role in Weather and Climate. The air never remains static in this layer. IT IS VERY NICE ARTICLE. VERY INFORMATIVE ANSD USWFUL FOE IAS EXAM—THANKS. This is called Normal Lapse Rate. The gravitational attraction* between the earth and air molecules is greater for those molecules nearer to earth than those further away — they have more weight — dragging them closer together and increasing the pressure (force per unit area) between them. Therefore, at a place, if the air is dense for instance near the Earth’s surface (due to Gravity), the atmospheric pressure will be more. The air is a mixture of several gases and it encompasses the earth from all sides. Pressure Gradient Force.

This pressure is called atmospheric pressure. Ocean CurrentsWaves and the ocean currents … cause of The major of atmospheric pressure, The force of wind & the light reflection; Regulates combustion & avoids quick burning Adopt the 3 Strategies for Success in the UPSC Civil Services Exam. Atmospheric pressure changes as the height or altitude increases. The first version of his climate classification scheme appeared in 1918, and he continued to modify and refine it for the rest of his life, the last version being published in 1936. Very Nice article. Stratosphere is found just above the troposphere. Higher percentage indicates that the air-water mixture is more humid. ii) Air pressure at sea level is lower than at the mountain top. The temperature here is nearly constant, and hence, it is called tropopause. It helps in stopping the ultraviolet rays harmful to the life and maintains the suitable temperature necessary for life. This is the most important layer of the atmosphere because all kinds of weather changes take place only in this layer. The environmental temperature decreases with increasing height of the atmosphere. Despite high vertical pressure gradient, there is weak upward wind because the pressure gradient gets weakened by the Gravitational force. 2. large value of coriolis force. Tides 3. The millibar (mb) is an expression of force per surface area. Frictional Force – It affects the speed of the wind. It is the movement of weathered materials down the slope due to gravitational forces. Radio waves transmitted from the earth are reflected back to the earth by this layer and due to this, radio broadcasting has become possible. Similarly, carbon dioxide (and water vapour) is found only up to 90 km from the surface of the earth. Meteorologist s describe the atmospheric pressure by how high the mercury rises. The temperature here starts increasing with heights. Water vapour also contributes to the stability and instability in the air. Carbon dioxide is largely responsible for the greenhouse effect. During the condensation, water vapour gets condensed in the form of droplets around these dust particles and thus clouds are formed. This is very important from UPSC point of view. ClearIAS Team has been receiving a lot of support and encouragement from our loving readers for our easy-to-understand articles on Geography. Movements of ocean water are also affected by external forces like the sun, moon and the winds.The major movements of the ocean waters can be classified into three. These are alluvial f, On 21st June, the northern hemisphere is tilted towards the sun. They are the highest mountain ra, The Great North Indian plains are homogeneous surfaces with an invisible slope. It is the third layer of the atmosphere spreading over the stratosphere. Thanks for sharing this. It is the lowermost layer of the atmosphere. Troposphere contains dust particles and water vapour. The upper limit of the stratosphere is known as stratopause. 3. inflow of air at upper level of atmosphere. Its maximum amount in the atmosphere could be up to 4% which is found in the warm and wet regions. It is transparent to the incoming solar radiation (insolation) but opaque to the outgoing terrestrial radiation. UPSC CSE Mains 2017 General Studies 1 (GS 1) Question Paper.
