Canadian geophysicist Tuzo Wilson realized that this age progression could result if the islands were formed on a surface plate moving over a fixed volcanic source in the interior.

加拿大地球物理学家 Tuzo Wilson 意识到，如果一块在内部固定火山源上移动的表面板块形成了岛屿，就会导致岛屿年龄增加。

As the plate moved slowly northwest, new volcanic islands would have formed as the plate moved over the volcanic source.

当板块缓慢向西北移动时，新的火山岛就会随着板块的移动，在火山源处形成。

The oceanic volcanic islands and their hot-spot trails are thus especially useful for geologists because they record the past locations of the plate over a fixed source.

海洋火山岛和它们的热点轨迹对于地质学家尤其有用，因为它们记录了过去的板块在固定地点之上的位置。

It works by using a power source to pump 10 kV of juice to an electrode, which then polarizes a dielectric plate, causing it to attract your body hair.
