Answer:
The population density is low in Karnali province because of the domination of extremely high mountains, steep terrain, lack of natural resources, lack of soil, bad climate conditions, lack of oxygen, etc.
Step-by-step explanation:
Nepal is a country that has a very uneven population distribution. The majority of the population is located in the plains in the southern and southeastern part of the country, while the rest of the country has little to no population. The reason for this is simple, these parts are the only ones that provide good living conditions, while the other ones don't.
One of the provinces that have a very small population density is Karnali. This province almost entirely occupies territory dominated by medium-high and very high mountains. The northern part of the province goes up to 6000, 7000, and even above 8000 meters above sea level. The climate is very hostile here and oxygen levels are very low. There isn't any vegetation in much of the province nor there is soil. The terrain is very risky and very steep. Natural resources are lacking and all in all, it is impossible for people to live in most of this province.
