Did you know that plate tectonics didn't always exist on Earth!? Until
now, I used to think tectonics started pretty much as soon as the Earth
was born, but apparently the Earth was still too hot in its interior to
start the plate tectonics process, though volcanism and other types of
subduction still happened. Apparently, tectonics started only 2 billion
years ago, less than half-way into its current age.
