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
Answer:
The vast majority of European countries will have problems because of population decline, with the ones in the eastern half of the continent being more affected.
Explanation:
As a whole, Europe is a continent that is having big problems with population decline. Just three countries in the continent experience slight population growth, while all others either stagnate or experience a decline. Now when it comes to birthrates and death rates, the differences are minuscule across the continent, but migration is something that makes the difference better.
While both the western and eastern half have low birthrates, the western, richer side doesn't really lose population but has a rough stagnation. This is due to the fact that it is an attractive destination for migrants, including migrants from the poorer eastern half of Europe, so the numbers are relatively static. The eastern half of Europe though, not just has low birthrates, but it also losses a lot of its population because it migrates toward the western half in search of a better life. Also, it is not very attractive for migrants from other regions, so it experiences a rapid population decline. The two most extreme cases in the last three decades are Macedonia and Bulgaria, each losing roughly between 20 and 25% of their populations.
Answer:
Earth's rotation and the gravitational pull of the sun and moon create tides on our planet due to large size if sun .
The sun also plays a role in the formation of tides,
Explanation:
in you can say that everything is interconnected to each other because the rotation and revolution of Earth takes place around the sun the lunar phases is also due to the sun and the tides happening on the ocean or any water bodies are due to the large size of sun and the gravitational pull and also the gravitational pull of moon so everything adjust interconnected to each other due to sun and moon
