What are the ages of hotspot volcanoes relative to each other?

Hotspot volcanoes vary significantly in age, typically forming a chain where the oldest volcano is furthest from the hotspot's current location. As the tectonic plate moves over a stationary hotspot, new volcanoes are created, resulting in a sequence that shows a gradient of ages. For example, the Hawaiian Islands exhibit this pattern, with the Big Island being the youngest and the older islands like Kauai and Niihau showing progressively greater ages. This age progression reflects the movement of the Pacific Plate over the fixed Hawaiian hotspot.
