Question

which type of geographic tool would best help show where immigrants to the us moved over time?
○ a bar graph showing total immigration numbers
○ a world map showing immigration routes
○ a us map showing population distribution
○ a timeline of changes in immigration policies

Explanation:

A world map showing immigration routes would display the paths immigrants took to the US over time. A bar - graph shows numbers not movement paths, a US map of population distribution doesn't show where immigrants came from or their routes, and a timeline of immigration policies doesn't show physical movement.

Answer:

B. a world map showing immigration routes
