The gravity model generally demonstrates that
A)two cities that are far apart can have a lot of interaction.
B)one city can have much activity within its own bounds.
C)two large cities interact more than a large city with a small city.
D)the largest cities have little interaction with other places.

Question

Quizplus · Accepted Answer

The gravity model states that the interaction between two places is directly proportional to the size of the two places (usually measured in population) and inversely proportional to the distance between them. Thus, two large cities (with high population) will interact more than a large city and a small city (with low population). Option A is incorrect because the gravity model implies that distance does have an impact. Option B is incorrect because it focuses on activity within a single city, whereas the gravity model is concerned with interactions between different places. Option D is also incorrect as it implies the larger cities have little interaction, which is opposite to the principle of the gravity model.
