黄石公园的超级火山和热点有什么关系?

How is Yellowstone's supervolcano related to a hotspot?

黄石位于北美板块下方的地幔热点之上;随着板块西移,热点先后在今天的俄勒冈、爱达荷到黄石留下一串火山痕迹,黄石是其中最年轻、仍在活动的一个。
Yellowstone sits over a mantle hotspot beneath North America; as the continent drifted west, the hotspot left a track of volcanism from Oregon/Idaho to Yellowstone, with Yellowstone the youngest and still active.

#黄石 #热点轨迹

什么是地幔热点,为什么夏威夷群岛排成一串还越来越老?

What is a mantle hotspot, and why do the Hawaiian Islands line up and get older along the chain?

热点是地幔深处一股相对固定、上升的炽热物质柱(地幔柱);太平洋板块缓缓移过它,火山就在不同位置依次喷发,于是形成从东南向西北年龄递增的岛链。
A hotspot is a relatively fixed upwelling plume of hot mantle material; as the Pacific plate drifts over it, volcanoes erupt at successive spots, forming the Hawaiian chain whose islands get older from southeast to northwest.

热点和普通的火山(比如环太平洋火山)有什么不一样?

How is a hotspot volcano different from ordinary ones like those around the Pacific?

普通火山多长在板块边界,热点火山却长在板块中间,由地底一股固定的热柱顶出来,所以常常孤零零地在海洋里冒出一座岛。
Most volcanoes sit on plate boundaries, but hotspot volcanoes rise in the middle of plates from a fixed hot column below, so they often poke up lonely islands in the ocean.
