Plate Tectonics May Grind To A Halt, Then Start Again
Plate Tectonics May Grind To A Halt, Then Start Again
ScienceDaily (Jan. 7, 2008) — Plate tectonics, the geologic process responsible for creating
Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair.
Scientists have assumed that the shifting of crustal plates has been slow but continuous over
most of Earth's history, but a new study from researchers at the Carnegie Institution suggests
that plate tectonics may have ground to a halt at least once in our planet's history -- and may
do so again.
