What will happen if the earths axis is not tilted?

Answer 1

When an earthquake happens, the Earth's axis is shifted by a few centimeters, and the length of the day is also changed slightly. This is caused by the mass displacement of matter affecting the inertia of the Earth.

Answer 2

Nothing, really, for now. The recent earthquake in Japan caused a shift in the Earth's axis and made the years longer by 1/64 of a millisecond. But in hundreds of millions of (modern) years, it will no longer be 365 days in a cycle; it will be around 390.

Answer 3

Answer 4

it would cause a earthquake arcoss the world and we could fall out of the gravtational pull from the sun and die
