Look at a globe and see how the continents sort of fit into each other if you smoosh them together. At one point, we used to be all one continent. But not anymore.
Over the next millions, billions of years even, our continents will be bumping into each other again, causing all sorts of annoyances for those still living on land masses. You might be able to step off the Aleutians and onto Hawaii - but Hawaii won't be warm anymore. If you own vacation property on Hawaii, you will eventually be screwed - about 2.3 billion years from now. I advise you to sell now.
I want to build my house on the San Andreas Fault. No, not near... I want it on the fault with the living room and kitchen on the North American plate and the bedrooms on the Pacific plate. And I expect the federal government will pay to rebuild my house if anything goes wrong.
If it wasn’t for global warming, george W bush, right wing Christians, or a god who couldn’t build a planet that didn’t have shifting plates or something, then the winds of the ocean waves would not be tearing down the shore line that was created billions of years ago and NEVER CHANGED by earth mother Giai until all the former got involved.
