A heard of sheep moves up in the mountain to graze during summer and migrated to the valley during winter what type of migration do the sheep follow

Answer: Seasonal migration

If the herd of sheep moves up in the mountain to graze during the summer, and then to the valley during winter, the type of migratory pattern that they follow is seasonal. This means that the sheep change their location based on the season of the year. This is caused by changes in weather, which in turn affect the vegetation of each area.
