Hurricanes, tornadoes and bigger bodies of water always go clockwise in the Southern Hemisphere and counterclockwise in the Northern Hemisphere. This directional spinning has to do with the rotation of the earth and is called the Coriolis force.
The magnetic south pole was discovered off the coast of Wilkes Land in Antarctica.
There is zero gravity at the centre of earth.
Earth orbits the sun at an average speed of 29.79 km/s (18.51 miles/sec), or about 107 000 km/h (about 67,000 miles/hour).
