How may have geography influenced the Mongols and territories they conquered?
Since there was the Himalayan mountains, the Mongols were not able to cross/climb them, so therefore they did not conquer much of India. Also, it says that early in their history, the Mongols developed skills that were necessary for nomadic living. So they developed ways to live, just like their climate. As you can see, they conquered areas around their climate/where they live, so they adapted quickly to the fighting conditions, which made combat easier.
