How can things like earthquakes shift the axis of earth?

729 views

So, when you attach a tiny fan to a tiny boat, and point it at the sail, the boat doesn’t move because the fan moves the boat backwards, and the sail moves the boat forwards.
(Edit: I’ve been proven wrong about the boat thing, so ignore that)

Following this logic though, how can earthquakes be able to influence our axis, and our day/night cycle length?

The boat has force acted on it, and will move over time. The problem with your analogy is that you forget just how big these land masses are in relation to the rest of the earth. Even then, the changes are minuscule. Hundredths of a second, up to a second at a time.
