Really? The concept of angular momentum (and rotational forces in general) is a pretty unanimous realm regardless of scale.
Why does the earth spin?

Dad .... ' What TF is angular momentum ? '
.... a couple of years down the line
Dad .... ' Why does the water going down a drain in Australia spin in the opposite direction to here ? '
* be prepared *

Nope.Four numbers, 2012, im worried are you?
Were you worried in 1998,1999,2000 and 2004 also?

True fact 3 - The earth isn't actually round...
its an Oblate Spheroid. Its wider at the middle. Like my missus.
(Never thought I'd get to say 'oblate spheroid' in a forum for the purposes of legitimate discourse.....!)

Really? It's just the rotational analogue of Newton's laws of (linear) motion. The only time you have to make adjustments is on the very small (quantum) scale and in the context of very strong gravity (general relativity) and very high velocity (special relativity).

Simple answer to that question, it doesn't.

Trundle wheel.
Lies. It's because people can get mac10 in 3 mins, so people be running everywhere, which through friction of people running in the same direction (as highlighted above) it turns the earth.

Surely one side of the planet will be heavier?
Given that though, why would it spin weather its on a 45 degree angle or 90 degree angle?
Gravity from space?

Earth spins due to people running on top of it. Newtons 3rd law of motion says for every action there will be an equal and oppisite reaction hence we see 4 bn people mostly walk and/or drive west where all the money is and cause the earth to go in the oppisite direction thus provoking the earths continual spin

Don't quote me on this but I read from a reliable sauce (and I do believe this is the most plausible raisin) that the big man himself is essentially "plate spinning". The planets in our solar system sit on invisible tables and he keeps them spinning for both entertainment and also to allow everyone on earth their fair share of Sunny Delight.
