Common Mistakes:
A common misunderstanding is that intermontane basins are rugged and unsuitable for habitation, which is incorrect for the Aizawl Basin.
Explanations:
Intermontane basins are depressions or valleys located between mountain ranges. In Mizoram, these basins, such as the Aizawl Basin, have relatively flat terrain compared to the surrounding hills. This flat terrain is conducive to agriculture and supports human settlements, making them suitable for cultivation and habitation.
