As the plate continuously moves across that spot, a trail of progressively older volcanic deposits is left at the surface. The Hawaiian Islands are a good example of this.

However, the Hawaii hotspot is more than 3,200 kilometers (1,988 mi) from the nearest plate boundary; while studying it in 1963, Canadian geophysicist J.
