This is chapter 4 of NCERT Geography (Our Environment) Class 7 Textbook titled AIR where I have talked about the composition of air which contains nitrogen, oxygen, carbon dioxide etc. The greenhouse gases and greenhouse effect has also been explained. The structure of the atmosphere which consists of troposphere, stratosphere, mesosphere, thermosphere and exosphere has been understood. The different phenomenon in these different layers has been discussed. Insolation, temperature and air pressure has been understood. Then we have understood what permanent winds, seasonal winds and local winds are. The 3 different types of rainfalls are discussed which are convectional rainfall, orographic rainfall and cyclonic rainfall. Watch the video to know more about air and associated phenomenon.

Not all who "teach" can make people understand the content. U r one such mentor, whose explaining skills are just outstanding. You teach as if u r narrating a story and not exactly "teaching" !

Sir i have 2 question , (1)~~thermosphere me nitrogen and oxygen dono hoti hai to oxygen ka kam hi burn karne kaa hai to thermosphere me kyu nahi ho raha burn ???
(2)-- sir sun to upper hai to amara atmosphere structure hair usme hum jab troposphere to exosphere pr jate hai to heat to high kyu mahi hoti ??

[@TRA]

Nitrosomonas bacteria first convert nitrogen gas to nitrite (NO2-) and subsequently nitrobacter convert nitrite to nitrate (NO3-), a plant nutrient. Plants absorb ammonium and nitrate during the assimilation process, after which they are converted into nitrogen-containing organic molecules, such as amino acids and DNA.
