EFFECTS OF ATMOSPHERIC PRESSURE:
Atmospheric pressure is defined as the pressure exerted on an object by the weight of the air above it. The atmospheric pressure on the Earth's surface at sea level is about one hundred thousand pascal, i.e., 100 kPa. If such an enormous amount of pressure is acting on us, why do we not feel it? This is because the pressure of the blood in our blood vessels and that of the other fluids present in the body balances out the atmospheric pressure. Atmospheric pressure is measured using an instrument called barometer.
If the pressure of atmosphere is changed suddenly, the blood vessels in our body will burst due to the pressure of the blood and other fluids inside. This is why astronauts have to wear special pressurized suits- there is no air and , therefore, no air pressre in space.
Effects of the atmospheric pressure :
1. Atmospheric movements : Vertical movements of air are air currents. The ultimate cause of these air movements is the pressure differences caused due to unequal distribution of the heat of the sun.
2. Clouds and fog : Fogs and clouds consists of condensed water vapours as particles small enough to remain in suspension. Clouds are formed mainly by adiabatic cooling of rising air. Air expands as it rises and such expension without addition of heat lowers the temperature leading to clouds formation. Clouds are also formed to a limited extend due to mixing of air currents.
3. Rainfall : The source of all precipitation is clouds. Cooling of moisture bearing air explains al precipitations.

When I have not joined Abhyas Academy, my skills of solving maths problems were not clear. But, after joining it, my skills have been developed and my concepts of science and SST are very well. I also came to know about other subjects such as vedic maths and reasoning.
We started with lot of hope that Abhyas will help in better understnding of complex topics of highers classes. we are not disappointed with the progress our child has made after attending Abhyas. Though need to mention that we expected a lot more. On a scale of 1-10, we would give may be 7.
Usually we see institutes offering objective based learning which usually causes a lag behind in subjective examinations which is the pattern followed by schools. I think it is really a work of planning to make us students grab the advantages of modes of examination, Objective Subjective and Onli...
