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?

The Earth's physical factors influence population density by being a key determinant in which people choose to reside. ... When there is an increase in population, birth rate is high, and the age structure of that population is forming like a pyramid which represents more people comprise the younger generation.

Ithink it’s around 500 million or something. kinda scary honestly but that’s just my opinion.

Well, both latitude and intensity of light affect temperature because, the higher the light intensity, the higher the temperature and since latitude is the measure of how close you are to the equator, then the closer to the equator you are, the higher the temperature is.
