Trivia: Gold was deposited into Earth’s crust billions of years ago by what?
Solar flares
Volcanoes
Tsunamis
Asteroids
The correct answer is Asteroids
So why is this answer correct? : During the Precambrian era (4.6 billion to 541 million years ago) asteroids from outer space inundated Earth, crashing into its surface. Upon impact, they deposited gold deep into Earth’s crust, where it remained until it was found by ancient civilizations. There is more gold deep inside Earth’s core (along with other precious metals) from when our planet was first formed, but it is unreachable.
