Video: The process of making the Earth's crust lose a lot of gold and silver

The solar system began to form around 4.6 billion years ago in the form of gas and rotating dust. These materials merge together to form rock, small rock bodies and finally large planets.

The evaporation process causes the early crust to lose volatile elements such as gold, silver, and zinc oxide.

But scientists have long wondered about the difference in composition between the Earth and meteorites that contribute to it. The answer seems to be in the history of Earth's collision.

The early Earth often collided with other celestial bodies, the force exerted enough heat to turn the soil into magma or heat.

New studies show the evaporation process causes the early Earth's crust to lose volatile elements such as gold, silver, and zinc oxide.
