Earth's core density of the planet Earth is on average 5,515 kg / cu.m., making it the densest planet in the solar system. But if the only measure the average density of the Earth's surface and measured just 3,000 kg / cu.m, which causes that conclusion. There must be other objects A denser core in the world. During the rise of the Earth about 4.5 billion years ago. The melting could cause a material with a density greater than flow into the Earth's core, while the matter is less dense than Earth's crust is covered. This makes the core composition is 80% iron, nickel, and molybdenum, as well as a lighter weight than the other. But while the matter is more dense. Such as lead and uranium There is little than can be combined with lighter elements have. Substances and those still on earth. Earth's core is divided into two phases.
