Influence of Earth's physical factor on population density is explained below:
Explanation:
- Earth's physical factors influence the population density in such a way that it becomes the key determinant for people to choose where they should reside.
- earth has both extremes of surviving in a particular area of non-survival areas were humans cannot survive.
- People most probably choose the areas of survival based on their basic needs the support their survival (for example source of food, water resource, climate conditions, availability of life-supporting resources, etc)
- When population increases in an area the birth rate also increases with a greater number of young people and age structure becomes a pyramid representation with young people existing more than old ones.
