1.) An asteroid hit at an angle to slow the Earth's rotation and to increase its axial tilt to give birth to seasons?

2.) An asteroid passed through the crust like a bullet causing little damage externally but changing the magma flow to decelerate the Earth's rotation? It would still leave a creator but the bulk of the impact would be absorbed by the inside of the Earth.

3.) An asteroid struck such that the polar caps melted or the water was forced out of the oceans?
