Simple Explanation
Desert regions में rainfall बहुत कम और reliable water sources सीमित हो सकते हैं। इससे drinking water, agriculture, livestock और permanent settlement कठिन होते हैं। इसलिए चौथा विकल्प सही है। Dense river systems, fertile soils और high rainfall deserts की सामान्य विशेषताएं नहीं हैं। परीक्षा में aridity और water scarcity को desert population distribution के मुख्य physical factors के रूप में याद रखें। / Desert regions usually receive very little rainfall and may have limited reliable water sources. This makes drinking-water supply, agriculture, livestock raising, and permanent settlement difficult. Therefore, the fourth option is correct. Dense river systems, fertile soils, and high rainfall are not typical characteristics of deserts. In examinations, remember aridity and water scarcity as major physical factors limiting desert population.
