The Voice of Our Earth 14.25min – Earth is about 4.54 billion years old. It is the only planet not named after a god. The Earth is the densest planet in the Solar System – mostly iron, oxygen & silicon. It is not round in shape; it is geoid bulging towards the equator. Earth is the only planet in our solar system to have water in all 3 forms – liquid, solid, gas. 70% of the Earth’s surface is covered in water – only 3% is fresh, 97% salted. Of the 3% freshwater, over 2% is frozen in ice sheets & glaciers. Less than 1% fresh water is found in lakes, rivers & underground. One third of the Earth’s surface is partially or totally desert. The Earth is struck by lightning 100 times per second i.e. 8.6 million times per day. The rotation of the Earth is slowing down – approx 17 milliseconds per 100 years & will take 140 million years before it has 25 hour days. The Queen of the U.K. is the legal owner of 1/6 of the Earth’s land surface.
