Distinguish between the following forces and choose the force that would be most likely to connect two different regions where there are people changing residence locations.

A. runoff
B. globalization
C. migration
D. nutrient pollution

A. Runoff refers to the movement of water from rainfall or melting snow that flows over land and eventually enters streams, rivers, and other bodies of water. It is not directly related to human movement or connecting different regions.

B. Globalization refers to the increasing interconnectedness and integration of countries and cultures through the exchange of goods, services, information, and ideas. While globalization can involve the movement of people, such as increased immigration or international travel, it does not necessarily focus on connecting different regions for residential purposes.

C. Migration refers to the movement of people from one place to another, typically with the intention of settling in the new location. Migration can be voluntary, such as for economic or educational purposes, or forced, due to conflicts or environmental factors. Given that migration involves people changing residence locations, it is the most relevant force for connecting different regions where there are people changing residence locations.

D. Nutrient pollution occurs when excessive amounts of nutrients, such as nitrogen and phosphorus, enter a water system and disrupt the natural balance. While nutrient pollution can have significant ecological impacts, it is not directly related to connecting different regions or people changing residence locations.

Therefore, the force most likely to connect two different regions where there are people changing residence locations is migration.
