-Fertility rate: The factor which affects the growth of the population in the biggest way is the fertility rate.
-Mortality rate: A key factor affecting the growth of the population is the death, or mortality, rate. Just as the birth of new people increases the population size, deaths decrease it.
-Immigration and Emigration: Cross-border migration is the act of people moving from one country to another. It affects the population size of both the host and destination countries. Emigration is caused by a number of factors, such as fleeing war, finding education, seeking new jobs or joining family members. When a person emigrates from a country, its population shrinks.
The Pyrenees are a mountain range in the western part of Europe. This mountain range is a natural boundary between the Iberian Peninsula and the rest of Western Europe.
This mountain range has formed as part of the Alpine orogenesis. The Alpine orogenesis has been triggered by the movement of Africa toward Europe, so the pressure created between the African and Eurasian tectonic plates has managed to lift up the land and create mountains, including the Pyrenees.
The Pyrenees are considered as young mountain range, and their formation is still not ended, but instead they are still growing in size and elevation.
These mountains make up the border between the nations of Spain, on the south from them, and France, on the north of them. There is one very small nations located on the mountains themselves, that being Andorra.
