Question

Will plate tectonics eventually turn off and cease to operate on Earth? Why or why not?

Answer 1

Plate tectonics are driven by the thermodynamics of the lava underneath the plates--it is possible that it will eventually stop (once the core cools off completely). However, last time I read about this, they were projecting that this would happen AFTER the sun will supernova and destroy the planet anyway.

Answer 2

when did they predict that about the sun?

Answer 3

no because they go in a repetitive movement and sometimes shifts into each other

Answer 4

Thanks

Answer 5

the sun will die in ~5 billion years
To be exact, it wont supernova (it doesn't have enough mass) but will become a red dwarf--in doing this it will expand at first and devour the earth.

Answer 6

But the earth will possibly survive - just not life on it. The Kepler telescope recently discovered an exoplanet orbiting a red dwarf which was probably temporarily engulfed when the star became a red dwarf.
