1. Earth is the only planet in the Solar System to have water in its three states of matter: as a solid (ice), a liquid (sea, rain, etc.) and as a gas (clouds).
2. Earth is almost five billion years old, although life has only existed on the planet for the last 150 million to 200 million years.
3. Earth is gradually slowing down. Every few years, an extra second is added to make up for lost time. Millions of years ago, a day on Earth will have been 20 hours long. It is believed that, in millions of years time, a day on Earth will be 27 hours long.
4. Earth has a powerful magnetic field. This phenomenon is caused by the nickel-iron core of the planet, coupled with its rapid rotation. This field protects the Earth from the effects of solar wind.
5. The Earth is, in fact, not really round. It is called an oblate spheroid meaning it’s slightly flattened on the top and bottom poles.
6. Most people believe that Death Valley, California, U.S.A. is the hottest place on Earth. Well, occasionally it is, but the hottest recorded temperature was from Azizia in Libya recording a temperature of 136 degrees Fahrenheit (57.8 Celsius) on Sept. 13, 1922. In Death Valley, it got up to 134 Fahrenheit on July 10, 1913.
