1:09:15 Since the earth is in geoid shape, the polar region is closer than the equator which help the gravitational force to pull the atmospheric pressure towards it more strongly in poles than the equator.. that is the reason their is difference in height of the troposphere
Variation in Troposphere is because the insolation is direct on Equator so the particles raised high due to Convectional Currents. Also, At Poles gravitational force is strong which attracts particles. BTW sir you explain very well and if there is any award of Best Sst Teacher of Universe so you always win that......
Thank you so much for your kind words! We are so happy to hear that our videos are helping students to overcome their fear of geography. We will continue to work hard to produce quality content that is both informative and educational.
At pole gravity pull is more stronger than at equator due to the geiod shape of the earth.Also at equator the solar insolation falls direct which causes conduction- convection phenomenon as a result large airmasses are formed pushing the troposphere height to 18km whereas at the pole the their is less insolation, thus the height of the troposphere is upto 8km.

Troposphere at Equator 18km nd height near poles 8km,this is because heat is transported to great heights by strong conventional currents 2nd one reason: because of the strong gravity

Sir the troposphere height at the equator is most coz of the heigh insolation on ITCZ, the air at equator rises upto a height though the troposphere height at equator is most,I think so🤔
troposphere is thicker over the equator than the poles because the equator is warmer. Heat differential on the planet's surface causes convection currents to flow from the equator to the poles. This implies that the warmer the weather, the thicker is the troposphere.
Thank you for your feedback! We're working hard to ensure that our videos are as comprehensive as possible. We'll be sure to include information on the forces affecting the velocity of wind in our next video.

1:09:34... the height vary near poles and at equator because near poles gravity is higher and near equator conventional currents leads to expand the length (in this air masses goes upward due to direct sun rays)

i have a question sir, you said that to eliminate the effect of altitude on pressure we calculate the pressure of that place at sea level to draw isobar, then why we dont use the same formula to calculate the isotherm of a place. bcoz temperature also decreases with altitude? plz guide. thank you
Thank you for your comment. You are absolutely correct that temperature also decreases with altitude. To calculate isotherms, scientists use a different formula to account for the decrease in temperature with altitude. I hope this clarifies your question. Please don't hesitate to reach out if you have any other questions.

1:09:22 sir the troposphere hight is high in equator beacause the solar radiation is come directly to the equator and form low pressure but in poles there was not sufficent amount of solar raditation come on the poles that's why in equator thehight of troposphere in equator is short sir jasie mujhe samajh aya mene bataya agar galat ho to bata dena

The troposphere on equator is 14km because of the radiation of the sun. These direct falls on earth's equator and forming conventional current so the atmosphere in troposphere is more in equator. And yhe gravity of earth attract the poles so that the atmosphere of the poles is less than that of equator.

Sir you teach very well but i would like to correct you that in sub polar low, air from sub tropical high is not warm air but it is the cold air result of collision of warm air and cold air at sub tropical high.😊

troposphere is thicker over the equator than the poles because the equator is warmer. Heat differential on the planet's surface causes convection currents to flow from the equator to the poles. This implies that the warmer the weather, the thicker is the troposphere.
Troposphere height is 8 km at pole while at equator is 14 km due to high pressure at pole and strong gravity
One topic missed in this video is forces affecting the velocity of wind.

Sir due to gravity troposphere Ki height less in polar region n high in equator…… if I m correct pls respond
1:09:22
sir the troposphere hight is high in equator beacause the solar radiation is come directly to the equator and form low pressure
but in poles there was not sufficent amount of solar raditation come on the poles that's why in equator thehight of troposphere in
equator is short
