b) it might be crowded and lack enough jobs or housing.

d) the land is too empty.

1. if many people move into an area for better jobs, what will most likely happen to its population density?

b) it will decrease.
c) it will increase.
d) it will disappear.

1. a city has become overcrowded and expensive to live in. many families move to smaller towns nearby. what does this situation show about push and pull factors?

a) people are pushed away by high costs and pulled by cheaper living.
b) people are pushed by jobs and pulled by family.
c) people are pushed by war and pulled by schools.
d) there are no push or pull factors in this case.

Explanation:

• Question 22: High population density can lead to overcrowding and shortages of jobs or housing, which are common reasons for people to migrate out. Options a and d are incorrect as high density implies less open space and not empty land. Option c is too broad as not all people dislike living near others.
• Question 23: If more people move into an area (immigration), the population density (population per unit area) will increase as the population numerator in the density formula ($\text{Density}=\frac{\text{Population}}{\text{Area}}$) grows while the area denominator stays the same.
• Question 24: Pull factors attract people. Good schools and job opportunities are positive aspects that draw people (pull), while war, drought, and lack of food are push factors (drive people away).
• Question 25: When a natural disaster forces people to leave (out - migration), the population of that area decreases as the number of people in the area reduces.
• Question 26: In the city example, high costs (a negative in the city) push people out, and cheaper living in nearby towns (a positive) pulls them. The other options either have incorrect pairings (like jobs as a push in option b) or wrong factors (war in option c).

Answer:

1. b) It might be crowded and lack enough jobs or housing.
2. c) It will increase.
3. c) Good schools and job opportunities
4. b) The population decreases.
5. a) People are pushed away by high costs and pulled by cheaper living.
