"the population in the mountain regionis sparse and widely dispersed"? explain the statement.
Answers
Though it is reasonable, that actually isn’t a correct statement. Mountain regions aren’t always sparsely populated, especially if one considers the demographic situation of some countries in the past.
In the Americas, for instance, the most populated regions in Pre-Columbian times were Central Mexico, which is dotted by high plateaus and mountains, and the Central Andes, one of the most mountainous areas in the world. In Asia, one of the regions traditionally most occupied by peoples was the northern part of the Fertile Crescent, in the Zagros, Taurus and Armenian highlands.
As a whole, whether mountains will be sparsely populated depends on its relief, its climate, its soil quality and the availability of domesticated animals and plants adapted to the natural conditions of mountains. It also helps if those mountains happen to be full of valuabe mineral ores to prospect and trade.
If there are fertile valleys, rivers and lakes, hills and mountains that are not too steep and can be cultivated in terraces and things of the sort, then a mountainous region can be very livable and even sustain very large populations. Cases in point are, for example, Switzerland, the Caucasus, the Iranian Zagros, and the Bolivian high plateau.
