Well I’m no meteorologist, but it seems to me the closer you get to the equator the denser the air mass becomes. The farther away it gets from the equator, it obviously gets less dense. I do notice though that the purple are is Greenland, northern Russia and Northern America. Which leads me to believe that it’s more mountain land and it’s density is compared to that of cooler air.
Answer:
The population density of the city is 20,000 persons per square mile
Explanation:
Population density is defined as the total population living in a region divided by the total area of the region
Here
Population = 100000
Area of the city = 5 square mile
Density =
people per square mile
The population density of the city is 20,000 persons per square mile
