For my project it says "Circle all physical characteristics that are used as a part of your country's boundaries"
I am doing the country of India so wwhat would be an example of the physical characteristic used for a boundary I suppose?
I'd start with the Himalayas.
Would rivers count
These are the boundaries I think there is : Bay of Bengal, Arabian Sea, is there more and are those right
Yes. Rivers can be physical boundaries.
Would this be correct : Arabian Sea, Bay of Bengal, Thar Desert, Ganges. Himalayas
Or do I have to name physical characteristics that are on the border
