question 17 of 25
a student examines the globe shown in the picture.
what are two benefits of using this globe as a model of earth?
a. it shows how human populations change over time.
b. it shows an object that is too large to be observed directly.
c. it shows the relative sizes of earths land ecosystems.
d. it gives details about how earth formed.

Explanation:

To determine the benefits of using a globe as an Earth model:

• Option A: Globes don’t show human population changes over time (this requires data/analysis, not a static globe). Eliminate A.
• Option B: Earth is too large to observe directly, but a globe (a scaled model) makes it observable. This is a valid benefit.
• Option C: A globe accurately represents the relative sizes of Earth’s landmasses/ecosystems (e.g., continents’ proportions). This is a valid benefit.
• Option D: Globes don’t explain Earth’s formation (that’s a geological/historical concept, not shown on a globe). Eliminate D.

Answer:

B. It shows an object that is too large to be observed directly, C. It shows the relative sizes of Earth’s land ecosystems.
