Question

a student moves to a different school and speaks to their new friends more than their old friends. this is an example of what geographical concept?
space
distance decay
place
flow
time - space compression

Explanation:

Distance decay is a geographical concept where the interaction between two places decreases as the distance between them increases. In this case, the student moving to a different school (increasing the distance from old friends) and speaking more to new friends (due to reduced distance - decay effect with new friends) fits this concept. Space refers to a general area, place is a specific location, flow is about movement (like of people, goods etc.), and time - space compression is about the reduction of time taken to cover distances (e.g., due to technology).

Answer:

Distance decay
