On earth our continents move...real...real slow. This is of course a good thing for sentient life.
I am trying to imagine/develop a world where...things move a bit faster...ok a lot faster, but in a regular pattern that doesn't generally result in two plates ramming into each other...the idea is that the plates would be in perpetual stable motion that is fast enough for a casual observer to see it moves during the course of a day.
Think of two continents that host separate nations that are in a cyclical war. Generally their lands are separated...but every time their two plates put them next to one another they have a battle royale, then after maybe a hundred years they come back in contact and do it all over again (the time frame is flexible).
I would like the plates/continents to be as large as possible while keeping the time waited between the nations coming into contact down to <250 years.
- Could a world such as this plausibly exist?
- How would the plates work, would the energy created make the planet uninhabitable?
- What would the world be like at the fault lines?
- How large could the plates/continents be and how fast would they have to move to allow the nations to battle at least every 250 years?
