After watching all these 57 lectures reading 11th NCERT was soo easy as all the concepts were crystal clear.
Hey brother, along with these lectures which all NCERTS should we suppliment? I am going to read all 6-12th but specifically with this series?
@@professorelixir3351 lectures which mam has made videos on, are of 11 NCERT (both) which actually has a high weightage in any civil service exam. Once you read NCERT books from 6-12 you will realise that with each subsequent standard same topics repeat.
@@darshantawte7435 Yes, I've read only 6&7th as just started. Thanks for the info 🙏
I had never find a such kind of teacher who is very hardworking like you for other people 👏...thx a lot mam...u deserve 👑this ...
Excellent teaching mam!! Your geography nd Mrunal sir's economics is best in India. Far better than other online education forums.
Ho gya clear ma'am
Mam ka lecture best hai, bahut hi achchhe se padhati hai (10/10)
but ye ppt rula deti hai 😢😢
Kash ye ppt bhi achchhi tarah se dikhai deta to world me geography ka best lecture hota.
Download the ppts from mrunal.org and open them along with the lecture.
the best supplement to the ncerts -the inclusion of previous years questions made me stick to the lecture completely .thank you, mam!
ma'am the diagrams are very small...u can make it more visible and distinct for better understanding of students
@@suryanshchaudhary2882 only lecture he show ho rhe h mam ke pr ppt nhi hai sahe se bta do

वाह मजा आ गया ......पहली बार ऐसा पढा़ई मैंने देखा 🙏🙏
That unbelievable teaching...hats off to you mam
this is great work.....sir
Even no any geographer have don this kind of work. thank you sir

Ho gya clear sir
Plzz focus on presntation also , lec delivery is gud bt screen presntation vry poor , kaafi small nd diagram is also too small
Great presentation....very well explained in lucid language. Thank you ma'am ❤️.
Sister app ka geography ka source kay hay
बहुत ही शानदार लेक्चर, धन्यवाद ma'm (IRS ऑफिसर 😎😎☺😊)
Old is Gold!
One thing i want to point out in this Video lecture is about Magnetic field Influence of Earth which has been said in this lecture that it spreads till Solar winds which is not true. It just protects our earth from solar wind. It doesn allow the solar particles to enter into the earths Atmosphere.....i find these Lectures very much useful and she is explaining very clearly but little fast but i am okay with the speed....Thanks for uploading these videos Mrunal...
thanx a lot , concept are being cleared so nicely in so lucid language ..plz continue as it is
These videos are still beneficial after 5 years thnku to all faculty..thnku
mam apaki video quality bahut low hai har video sunate hai hum...but map koi bhi dikhata ..please zooming map images...thank u

YOUR KNOWLEDGE AND THE WAY YOU DELIVER IT IS AUSPICIOUS,IN FACT YOU ARE FANTASTIC,WOULD BE MORE IF U DICTATE IT A LITTLE CLEAR ND SLOW ONLY IF YOU ARE USING BOTH LANGUAGES .....PLEASE.........
धन्यवाद मॅडम और मृणाल सर.....जय महाराष्ट्र
ma'am your explanation was very good.but the only flaw I found is "the continental crust is heavier not the Oceanic crust".
I think she said the Oceanic crust is denser!
Bhai oceanic crust heavy because of basalt present in it not continental
Although the video was not much clear but that didn't hindered the understanding of the topic. Thank you very much 🙏🙏
Should I study from this lectures in 2023.?

Dear Rajtanil Ma'm, why does google show the location of Mariana trench north-west to Northern Mariana islands? is there any rational behind it or its just a mistake that we can report to Google. I live in New Zealand and work as a software tech here and also i have been working on an application for Guam that i think is in the vicinity of this trench. There is other picture floating on internet that support your say that this trench is south-east to NMIs.

but why the polarity is alternate rather than being random...!
Mam ek dbt hai.apnai bola ki Jo alternative polarity ocean k andar create hota hai kuki wo rock jab molten state mai hota hai to earth ka polarity wo adopt kar laita hai.ek chis samaj mai nahi ayi ki kya yai hamaisa compulsory hai ki rock jab molten state mai polarity adopt karta uska conjugate rock ka polarity opposite hoga jab melting position mai hoga.agar compulsory hai to ku compulsory hai?
Thank you for all Intent and it's deed..
Guys,
it really sad that despite of having such a nice stuff over this very less likes ,comments and subscribe ,please spread the wild fire ..
Please read the description, powerpoint presentation is available to download the same that is used in teaching.
Where can we download the ppt
Very Thank full to your work sir & mam...
Done
The earth is expanding. Their is not enough force from the splitting sea floor to cause continental movement. If their was the lest possible path for a force would be to create a mountain rang up to the surface of the ocean. Similar to the Hawaiian islands .
The earth is expanding, this is why their is little to no sea level rising due to the pole ice melting.
Great work mam... helped me a lot......
Aap bhut ache ho acha pdhate ho voice is beautiful
👍
Mem apne bola earth apna pol change krti he to kis base pe bola..agar change hota he pole to humari position b change honi chaie

thanks a lot, u guys are great
Great job ma'am...👍👍
thanks sir . geo series..wonderful that is helping alot
I am unable to find such detailed explanation in GC Leong or Majid Hussain. Someone pls tell me the books to be referred to get such comprehensive info. Pls.
me too
have you found any book
Savinder Singh is good, but still not so much explained :)
kisi b university ki Bachelor and master course ki book le lo geo ki, hope it will clear your doubts.
Dear Mam, If the magnetism of earth reverses frequently, then are we yet able to record these changing times ? And does this effect never affects the functioning of the magnetic compass ??
@shahid You cannot because Chrons( time period to alternate the polarity) on average is over million of years. That is only only through mappping magnetic properties of ocean rocks one came to know that magnetic behaviour of earth changes across ages.
That is why its Geomagnetic reversal(Geo-earth surface related) not magnetic reversal.
Am I the only one who is unable to understand concepts through these lectures?
When U'll listen it 2-3 times than u will be able to understand
do read ncert first by mk sir in channel study with mk then u will get mam lecture
Yes you're the only one
@@Kashmiran nah..mam you have to read it first by google or any other book..then these lectures would be useful..if you are going only through these lectures then you wouldn't be able to understand the topics conveniently...i am.attending her lectures with google ..otherwise she will not make you understand the topics deep down...
I'm too not understanding
at 15:30 you show a diagram where the magnetic lines are originating from south pole . But according to convention we take origin of magntic lines from north pole and sinkng into south pole
can anyone explain that ?
Where we have geographical North Pole it is actually a Earth's South Pole and vice versa. This is because our compass north pole always points towards earth's south pole (opposite pole attract each other) so to make it consistent with compass, geographical North Pole is kept at earth's magnetic south pole so that it now compass north pole point towards geographical North pole (which is actually magnetically earths South Pole) . I hope this explains your question
Thanks
I'm in indebted to u maam
How can i download images? Plzz tell
