Question

which visual aid would be best for showing the difference between the sizes of planets in our solar system?
○ model
○ bar graph
○ concept map
○ line graph

Explanation:

A bar graph is effective for comparing quantities (like planet sizes) as it uses bars of different lengths to represent values, making size differences clear. A model might not scale well, a concept map shows relationships, and a line graph shows trends over time, not comparisons of discrete sizes.

Answer:

bar graph
