Earth is the 3rd planet of our Sun based solar system. Its a blue planet with 70% covered with water. It’s also green for the green forests. It has an area of 510 million squire kilometers. The concept of Earth has changed from early ages that it was flat and supported by animals to the symbols of a blue planet spinning around the Sun. This new concept of earth represents global unity. But the ancient idea of the Mother Earth remains in our minds. Its landscapes, natural events, various species, raw materials and soil all are strongly related to symbolism, religion, and art.
