If many children are born in an area, which process is active in population change?

Answer and explanation

Correct answer: Birth

Direct answer: A, birth. Birth is the process through which new individuals are added to a population. In this situation, many children are born in the area, so the birth process is clearly active and it tends to increase the number of people there. Follow the idea step by step: a child is born, the child becomes a new member of the population, and the total population receives an addition. A is correct because it names exactly the event described. B, out-migration, means people who already live in the area leave it; no such movement is mentioned. C, death, removes living members from the population and is the opposite event. D, erosion, means the wearing away and removal of soil or rock by water, wind or other agents; it is a physical geographical process, not a population process. Memory cue: births add people, deaths remove people, and migration moves people.
