Q: I heard about this but I'm not sure how they impact on the axial rotation of the Earth.
A: You are right. A large earthquake can cause a very minor change in the inclination of Earth's axis and rotation. This is not the strength of the earthquake that does this, but the associated change in mass in the crust.
If Earth stopped spinning on it's axis what would happen?
I know it would be constantly daylight but what would be the effect? Is there anyway you could help this situation?
I know there were spectroscopy tests done in the early 1920s that helped us determine the atmospheric and geological composition, but what about when we learned the rotational speed?
