There is variation in skin colour of people depending on the latitudes. For. e.g., people near the equator are dark since the sunrays are vertical and hence there is too much heat, while people in temperate or polar region are fair since sunrays in these regions are slanting due to increase in distance from sun. Hence, there is low temperature and colour of skin is fair.
