Geological Features of White Island and the Pacific Ring of Fire

The video explores White Island's geological significance, located at the junction of the Pacific and Australian plates. It explains the subduction zone dynamics, where the Pacific Ocean floor dives beneath the Australian plate, causing earthquakes and volcanic activity. The video also highlights the Pacific Ring of Fire, emphasizing the visible geological features and the interaction between the plates.
