All of the gold found on Earth came from the debris of dead stars. As the Earth formed, heavy elements such as iron and gold sank toward the planet's core. If no other event had occurred, there would be no gold in the Earth's crust. But, around 4 billion years ago, Earth was bombarded by … See more

Earth and the rest of the solar system formed about 4.6 billion years ago from a huge, spinning cloud of gas and dust. Over a period of about 10 million years, the dense center of the cloud grew very hot. This massive center became the sun. The rest of the particles and objects continued to revolve around the sun, colliding with each other in ...

Gold is a very rare substance making up only ~3 parts per billion of the Earth's outer layer (imagine 1 billion smarties in one place and only 3 of them were made of gold!). Its rarity and physical properties have made gold one of the most prized of the Earth's natural resources. When gold is found in rocks it is almost always in a pure state.

Pyrite and pyrrhotite are minerals known as iron sulfides. When iron sulfides are exposed to water and oxygen, a series of chemical reactions breaks down the iron sulfides and forms new minerals called sulfates. These sulfates take up more space than the original iron sulfides.

noun. an opening in the Earth's crust, through which lava, ash, and gases erupt, and also the cone built by eruptions. Our planet began as part of a cloud of dust and gas. It has evolved into our home, which has an abundance of rocky landscapes, an atmosphere that supports life, and oceans filled with mysteries.

Gold, in its pure form is not made - it occurs naturally in an elemental form. On a side note, the history of alchemy was largely based on the desire of people (probably kings!) to combine other (cheap and abundant) elements and compounds to make gold. ...

The origin of gold on Earth is a fascinating tale that defies common misconceptions. Surprisingly, gold does not form on our planet. It is instead forged deep within massive stars during the cataclysmic event of a supernova. Following a supernova explosion, gold, along with other precious elements, embarks on a cosmic journey …

Scientists believe that gold is about ten times more common on the surface than it should be. To explain how the gold we mine and use is made, there are two suggested explanations, and both involve massive asteroid impacts on the Earth. The first suggests that asteroids, which were formed in a similar way to the Earth, crashed into our planet ...

Gold is naturally occurring. When heated currents of fluid circulate under the Earth through rocks, it melts and picks up gold and other metals. Chemical differences in the fluids cause them to separate to a certain extent, creating concentrations in the form of lode deposits. This collection through superheated fluid means that areas with ...

How the Earth and moon formed, explained. The Earth formed over 4.6 billion years ago out of a mixture of dust and gas around the young sun. It grew larger thanks to countless collisions between dust particles, asteroids, and other growing planets, including one last giant impact that threw enough rock, gas, and dust into space to form the moon.
