What causes the older Hawaiian islands to go extinct?
As they age, the crust upon which they sit cools and subsides. This, combined with erosion of the islands once active volcanism stops, leads to a shrinking of the islands with age and their eventual submergence below the ocean surface.
Why are the Hawaiian Islands sinking?
Because the rate of ice melt has been increasing significantly since 1992 and the land is sinking due to a process called subsidence, Hawaii is particularly vulnerable to an increased rate of sea level rise in the future.
Why are the Hawaiian Islands different ages?
The reason for the Hawaiian Island chain’s correspondence in location and age is the Hawaiian hot spot, the place where magma rises from deep within the Earth and forms underwater volcanoes that grow to rise above sea level and create islands.
Will the Hawaiian Islands disappear?
The islands don’t last forever. The island erodes and the crust beneath it cools, shrinks and sinks, and the island is again submerged. Millions of years from now, the Hawaiian Islands will disappear when the edge of the Pacific plate that supports them slides under the North American plate and returns to the mantle.
How much longer will Hawaii exist?

Will Hawaii ever be underwater?

Reports of new-onset backache after epidural anesthesia vary from 2% to 31%.
