Such a parent process could be a previous decay, or a nuclear reaction.), and the process produces at least one daughter nuclide.
— that the US incessantly and continually runs propaganda psy-ops against every other country in the world.
And I’m not even including the venerable, old, out-in-the-open propaganda organs like Voice of America and Radio Free Europe (reminder: the Iron Curtain came down a quarter century ago).
These changes typically occur so slowly that they are barely detectable over the span of a human life, yet even at this instant, the Earth's surface is moving and changing.
As these changes have occurred, organisms have evolved, and remnants of some have been preserved as fossils.
