种子植物进入夏威夷群岛的唯一最重要的方法可能是作为食用其果实(如蓝莓、檀香)的鸟类消化系统中的种子,大约37%的非流行性种子植物可能是通过这种方式到达的。值得注意的是,许多成功到达岛屿的植物与其他植物不同,它们结的是肉质果实,而不是干种子,比如夏威夷的薄荷、百合和茄。被海洋分散的夏威夷种子植物只占非流行性...
How many Hawaiian Islands have volcanoes? What type of magma does a cinder cone volcano have? Is Mauna Loa a cinder cone volcano? How many active volcanoes are in the Ring of Fire? How many volcanoes have erupted in the last 100 years?
How are cinder cone volcanoes formed? How many active volcanoes are in the Hawaiian Islands? How much volcanoes are there in the world? How do earthquakes create mountain ranges? How can volcanoes initiate extinction events? How does a fissure volcano erupt?

There are a startling number of volcanoes on earth -- more than 500 "active" volcanoes in the world, about as many "dormant" volcanoes, and many volcanoes that have been deemed "extinct." As it turns out, these determinations are largely based on subjective interpretation or somewhat arbitrary...
And rather than a series of burned spots in the paper, you're getting a chain of volcanic islands... where the hot plume melts through the crust under the Pacific Ocean at one point after another—with active volcanoes on the younger islands that're now just above the plume, and the ...
