The earth ulis called a blue planet because of the presence of abundance of water in it. About 70 percent of the earth's crust is covered with water. And this imparts it with a blue colour as seen from the space.
The innermost four planets of our solar system are called the âterrestrialâ planets, which comes from the word âtelluricâ. It is derived from the Latin words âterraâ and âtellusâ, used to refer to Earth. The terrestrial planets (in order of their distances from the Sun) are Mercury, Venus, Earth and Mars.They are made mostly of silicate rocks and metals, with solid surfaces and atmospheres that range from thick (on Venus) to very thin (on Mercury). The terrestrial planets in our solar system orbit relatively close to the Sun, this gives them their other name; the âInner Planetsâ. 2  Earth is the most hospitable to life. 3  Mars may have supported life in the past, but there is no evidence that conditions have ever been life-friendly on Mercury or Venus.
