what helped create the layers of earth

Nov 16th, 2014

The major layers of the Earth, starting from its center, are the inner core, the outer core, the mantle, and the crust. These layers formed as the building blocks of Earth, known as planetesimals, collided and collapsed under their own gravity around 4.5 billion years ago. At that time, the heaviest elements (like iron and nickel) sank to the core, while the lighter elements (like silicon, oxygen, and carbon), rose to form the mantle and crust.
