Question

3
there are many different types of scientific investigations, including controlled experiments, observational field studies, the collection of specimens, and model building. which type of investigation is best used to study global weather patterns?
a. observational field studies
b. controlled experiments
c. the collection of specimens
d. model - building

Explanation:

To study global weather patterns, we analyze each option:

• Option A (observational field studies) would be limited as global weather is too large - scale to observe directly in the field comprehensively.
• Option B (controlled experiments) is not feasible as we can't control global weather conditions in a lab or controlled environment.
• Option C (collection of specimens) is irrelevant as weather patterns don't involve collecting physical specimens.
• Option D (model - building) is suitable. Scientists build computer models (like climate models) that incorporate various factors (such as temperature, pressure, wind patterns, ocean currents) to simulate and study global weather patterns. These models can help predict future weather trends and understand the complex interactions in the global weather system.

Answer:

D. model - building
