Answer :
Final Answer:
c) The law of gravity model because the law of gravity model is not one of Ravenstein's laws of human migration because it is a separate concept used to predict interactions between places based on population size and distance.
Explanation:
Ravenstein's laws of human migration are foundational principles in the field of migration studies. The correct answer is (c) The law of gravity model. This is not one of Ravenstein's laws explaining human migration.
Ravenstein's laws include:
a) The law of migration streams, which describes the tendency for migration to flow in specific channels or pathways.
b) The law of step migration, which explains that migrants often follow a series of smaller, intermediate movements before reaching their final destination.
d) The law of counter migration, which suggests that there may be return migration flows from destination areas back to places of origin.
However, the law of gravity model is not one of Ravenstein's laws. Instead, it is a separate concept used in geography and urban planning to predict the volume of interactions between two places based on their population size and distance from each other. It is not specifically related to the patterns and principles of human migration proposed by Ravenstein.
In summary, while the other options (a, b, and d) are indeed part of Ravenstein's laws of human migration, the law of gravity model is a distinct concept used for a different purpose in geographical analysis.
