How well do we know our planet? 1. The actual shape of Earth is not a sphere but an oblate spheroid or Geoid. This shape is similar to a sphere, but the poles are flattened and the equator bulges (due to rotation). The Earth is made up of layers. The Inner and Outer Core, the Mantle, and Crust.

The surface of the Earth is divided in to tectonic plates that float on the rocky mantle.  4. The inside of the Earth is very active with mountain formations, volcanoes and earth quakes occurring along the boundaries of tectonic plates. 5. Earth has less craters on the surface (compared to moon and few other planets) due to it's geological activities (like volcanoes & earth quakes) and movement of tectonic plates. 6. Earth revolves around the sun in its orbit at a speed of 67,000 mph (107,826 km/h)  7. The Earth i...

Almost about one thirds of a human life is spent sleeping! Randy Gardner, a 17 year old, (in 1962) holds the record for longest period without sleep that is 11 days (264 hours and 12 minutes)!

An average human takes 10-15 minutes to fall asleep. A cat spends 2/3rd of its life sleeping! A short and quick nap for just 6 minutes can improve memory! (Nope, I am not recommending a nap at work :p ) In the US, 16% of employers provide a napping area for employees! (I know your reaction at this! :D ) The ideal temperature for a good/qualit...
