what is migration class 8

Migration is the movement of an organism or a group of organisms from one area to another at a specific time each year. In the context of human geography, migration is a form of geographical mobility of a population between a geographical unit to another, generally involving a permanent change of residence. There are different types of human migration, including internal migration (moving within a state, country, or continent), external migration (moving to a different state, country, or continent), emigration (leaving one country to move to another), immigration (moving into a new country), return migration (moving back to where you came from), and seasonal migration (moving with each season or in response to labor or climate conditions) . People migrate for many reasons, including economic, social, political, and environmental factors.
