using four or more complete sentences, explain why new technologies are making physical features less of a challenge when creating and changing national boundaries.

We can explain why physical characteristics are becoming less of a problem when establishing and modifying national boundaries using the following means:Physical characteristics that made it difficult to enter or dwell in a certain location in the past eventually became that region's or country's national boundaries. For instance, since they were difficult to traverse, mountains, rivers, and deserts were utilized to define the boundaries of individual nations.These days, those features are less difficult to use because to the technology we've built. We can use helicopters or aircraft to cross mountains. In boats and ships, we travel over rivers and seas. To live in the desert, we can construct homes with cooling systems. Physical characteristics therefore no longer serve as as much of a boundary as they formerly did since they are less of a barrier. National boundaries are now far more heavily influenced by politics than by physical characteristics. Learn more about Geography here:https://brainly.com/question/876887#SPJ1
