Question

select the correct answer. what is a population pyramid? a. a key piece of information commonly included in special purpose maps b. a graphic that displays a country’s population broken down by age group and gender c. an area of a map that indicates what certain symbols mean d. a graphic that displays the spatial distribution of earth’s population

Explanation:

• Option A: Special - purpose maps have various info, but a population pyramid isn't just a "key piece" in them. It's a specific graphic, so A is wrong.
• Option B: A population pyramid is a bar - graph - like graphic. It shows the population of a country (or region) divided by age groups (like 0 - 4, 5 - 9, etc.) and also by gender (male and female). This matches the definition of a population pyramid.
• Option C: The area of a map that explains symbols is a legend, not a population pyramid. So C is incorrect.
• Option D: A graphic showing the spatial distribution of Earth's population is a population density map or something similar, not a population pyramid. So D is wrong.

Answer:

B. a graphic that displays a country's population broken down by age group and gender
