Question

explain why new technologies are making physical features less of a challenge when creating and changing national boundaries

Answer 1

Answer:

New technologies make physical features less of a challenge when creating boundaries. Many new technologies have been created to overcome these barriers. For example, a mountain range was once an impassable barrier. Now we have the technology that allows us to fly over the mountain or tunnel through it. We have created heating and cooling systems that allow us to live in extreme climates, such as desert or arctic regions. We also build dams that allow us to live near water sources or store water where it is scarce. These technologies allow people to create barriers for political reasons, rather than because of physical challenges.

Answer 2

Before things like mountains were typically boundaries since they were a pain in the butt to cross. But with modern planes, and depending on the mountian, cars, mountains aren't as big a pain anymore. Deserts might have also been a boundary before. Today you turn on the AC and drive straight across it. At least for technologically advanced western countries, there really isn't any geographic feature we can't easily get around.
