I understand that most scientists believe that the Earth's core is composed of iron, nickel and perhaps some other elements such as sulfur and oxygen. I also understand that they believe that the Earth's core formed during a time when the Earth was molten and that the core was formed by heavier elements sinking and compacting and lighter elements rising on convection currents. My question is if it was formed by this process why is it not composed of elements heavier than iron such as uranium?
