Cross-Sectional

Explanation:

Cross-Sectional study entails getting together information from a sample of people in order to round up or estimate the characteristics of a larger population at a single point in time. It simply look into if an association exists between an exposure and an outcome at an individual level.

It is knowing more about developmental changes without conducting an experiment over time. Groups of different age groups to have different conditions are selected and then, by the comparison of these groups you draw your personal conclusion about developmental changes over time.

idk if you found them already or not but you probably did but the one closer to sea level is raleigh.
