Uranium and the majority of the other heavy elementsâ¦ are formed by stellar nucleosynthesis in novas and supernovas. Heavy elements from the various sources in our galaxy combined with the mass of hydrogen that was the beginning of the formation our solar system around five billion years ago.
The widely accepted theory of how Earth was formed nearly 4.50 billion years ago is by core accretion. Earth's rocky core formed first, with heavy elements colliding and binding together. Dense material sank to the center, while the lighter material created the crust. Gravity captured some of the gases that made up the planet's early atmosphere. The planet's magnetic field probably formed around this time.
