How do the Earth's physical factors influence population density? When population growth increases in an area, what is happening to the birth rate and age structure of that population? (Site 1)

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.
