  15. Dear Mrunal Sir and Madam, thanks a ton for uploading the videos.
    One request, whenever madam explains anything on maps we don`t get to see which place is she ,pointing at that time, we only get to see the map. So, if you could get the focus towards the screen we all will get to know by the location of mouse or pointer which she might be using to point out the locations.
    Hope you will consider my request.
    Thanks in advance.

    And waiting for your next uploads in geography :-)


    1. sarkaari camera quality is quite poor. the ppts you see are directly captured from the harddisk, rather than from the screen. that’s why.

      1. Dear Sir

        Please teach in English

  16. Madam, very well explained and neatly presented. Could you please let us know that after completion of Geography, Environment & Biodiversity will be done…It would be great if you could help us here.. Thanks.

  17. Thnku very much Sir n Madam. Sir, I am also requesting plz upload other subject’s videos if classes is conducted

  18. Very good explanation

  19. Pls use pointer or mouse. Geography teaching without pointing to the place is not good, otherwise your lecture is very good.

  20. Mrunal Sir,

    I am unable to down load the following lecture “G3/P2: Landform Types- Plateaus”.
    Could you provide any alternative link.


  21. Thank you so much Mrunal sir and madam. kindly continue uploading the lectures.

  22. English Plzzzzzzzzzzzzzzz…………

  23. Dear Mam,

    Query regarding Fold mountains, In lecture G2- P3 as per your PPTs fold mountains formation only takes place at C-C convergence but now in lecture G3-P1 it has been stated that fold mountain can be formed by the collision between O-C Plates (Andes & Rockies). If so then whats the basic difference between two? because as per your lecture it says only volcanic mountains can be found at coastal region formed by O-C Convergence ex Andes & Rockies & fold mountains formation takes place during C-C convergence Ex Himalaya & Alps. Pl carify

  24. Please correct me if i am wrong, in Geography G3/P1 I heard students in background said Scandinavian countries as- Norway, Sweden and ‘ Finland’, as far as I know it is Norway Sweden and Denmark.

    NORDIC Countries:-
    Faroe lslands, Svalbard, Aland,Iceland, Finland, Denmark, Norway, Sweeden. (last 3 are Scandinavian countries named because of geographical location of Scandinavian mountains as mam said in her lecture.)

  25. In the second part of the lecture … I seriously didnt understand Inter-mountain Plateaus…. need help..

    thank you…

    1. never mind .. i figured it out myself

  26. I am not able to get the link for geophysical phenomena presentations. I can see only presentations related to either india or world geography. Please help me with the link for it
