Question

1. a country has a low birth rate, but many people are moving in from other countries. what will most likely happen to its total population? a) it will go down. b) it will go up. c) it will not change. d) it will disappear completely. 29. how can push and pull factors work together to cause migration? a) push factors make people want to stay, and pull factors keep them away. b) push factors make people leave their homes, while pull factors attract them somewhere new. c) push and pull factors always cancel each other out. d) push and pull factors only affect animals. 30. why is understanding population density and distribution critical when studying migration? a) it helps people learn where and why populations grow or move. b) it shows how tall people are in each place. c) it only matters to scientists who study weather. d) it tells us how old people are in a country.

Explanation:

• Question 28: Population size is affected by birth - death rates and migration. A low birth rate alone might suggest a stable or slightly declining population, but significant in - migration (people moving in) will add to the population.
• Question 29: Push factors (e.g., poverty, war in the home country) drive people away from their homes, and pull factors (e.g., job opportunities, better living conditions in a new country) attract them to a new place.
• Question 30: Population density (number of people per unit area) and distribution (where people are located) help in understanding patterns of population growth (e.g., in areas with more resources, population might grow) and movement (e.g., people might move from low - density to high - density areas for better opportunities).

Answer:

• 28. b) It will go up.
• 29. b) Push factors make people leave their homes, while pull factors attract them somewhere new.
• 30. a) It helps people learn where and why populations grow or move.
