Important Geophysical phenomena such as earthquakes, Tsunami, Volcanic activity, cyclone etc.,
geographical features and their location (examples: why are coral reefs located on the eastern side of the continents, why are there no volcanoes in the Himalayas, why Japan witnesses so many earthquakes, etc.)

For Geography we strongly recommend our own notes. You can get it in PDF format from here.

Pros:

Cons:

Doesn’t cover Industrial Locational factors. You can refer mrunal.org/geography for this.
Lengthy notes (can’t help. Geography is intrinsically broad and complex).
It is a compilation made from all the core books below.

Pmfias.com Geography + Mrunal.org Geography + Regular Current Affairs should be enough to cover geography for GS.
If you prefer reading geography from core books then continue reading.
There is no one single book for Geography that covers everything (Pmias.com Geography + Mrunal.org Geography + Regular Current Affairs should be enough to cover geography for GS).
Spectrum’s Geography is one book that covers 60-80% of Geography syllabus required for GS Geography.
These are books written from the academic perspective. Reading these books is an overkill unless you have opted for Geography Optional.
