Every weekend in summer, large numbers of people leave the hot desert climate of phoenix to head for vacations in the cooler climates of northern arizona. this is an example of a. permanent migration b. cyclic movement c. intervening opportunities d. commuting

The correct answer is B) Cyclic movement.

Permanent migration refers to when an individual or group leave their current place of residence in order to live somewhere else full time. This is why letter A is incorrect.

Commuting often refers to a person's travel from their home to their place of work. This is why letter D is incorect.

This is why B is the answer, as this movement happens at the same time everywhere. The term cylic implies that this movement happens at the same time yearly.

yes they have. but is this a true false question? if it is, the answer is true.
