The volcano continues to erupt building out its shield shape for about 500,000 years to 1,000,000 years. Eventually, the top of the volcano collapses and forms a caldera volcano.]]> 2023-08-25 03:18:54 UTC https://padlet.com/16134171/8o2mtq6kpah24n4c/wish/2672451841 16134171 https://padlet.com/16134171/8o2mtq6kpah24n4c/wish/2672453720 After the caldera collapses it gets filled in as the volcano continues to erupt and it slowly moves away from the hot spot.]]> 2023-08-25 03:20:46 UTC https://padlet.com/16134171/8o2mtq6kpah24n4c/wish/2672453720 16134171 https://padlet.com/16134171/8o2mtq6kpah24n4c/wish/2672516406 The erosional stage begins as soon as the volcano breaks the surface of the water. This stage includes erosion which slowly flattens the mountains.
