South-facing slopes are favourable for rural settlement locations in the cool temperate regions of the Northern hemisphere because they receive more solar energy. In these regions, the sun's rays are at a low angle during the winter, and by placing settlements on south-facing slopes, they receive more direct sunlight, which helps to keep the area warm. This is particularly important in areas where winter temperatures can be very low. Additionally, south-facing slopes often have better soil quality and drainage, making them more agriculturally productive.
