Final answer:
Nomadic groups often move due to a lack of resources, such as animals to hunt or scarcity of grazing land. They also relocate because of political and social changes, desertification, and competition over natural resources.
Step-by-step explanation:
An example of a reason a nomadic group would move to a new location is the lack of animals to hunt. Nomadic societies often rely on hunting, gathering, or pastoral activities for their subsistence. As primary gatherers in gatherer-hunter groups, women, for instance, might gauge the depletion of food resources and suggest moving when they have to travel too far to gather food.
Similarly, nomadic pastoralists may move due to a scarcity of grazing lands caused by desertification or competition with settled farmers. Moreover, changes in political and social realities, such as the rise of firearms, have historically caused nomads to move, either due to sedentarization pressures or conflicts over natural resources.
