Scientists believe all the gold on Earth formed in supernovae and neutron star collisions that occurred before the solar system formed. In these events, gold formed during the r-process. Gold sank to the Earth’s core during the planet’s formation. It’s only accessible today because of asteroid bombardment.

How does gold appear on Earth
Gold can occur as reservoir veins, commonly referred to as veins, in fractured rock. It can also be distributed in the earth’s crust. Most veins form deposits if heated fluids flow through auriferous gold, which traps the gold and concentrates it in new locations in the area.
Does the earth naturally produce gold
In its natural form, it is identified deep in the earth’s layers, where it easily transfers water, molten lava, volcanic eruptions and earthquakes. Geologists have found rare rocks 4.5 billion years ago.

Does gold come from space
Unlike other metals used in the earth’s crust, gold is mined from space. Stars are mostly made up of helium and hydrogen, which gives them light. In the core of a star, nuclear fusion generates energy. When your star’s life comes to an end, a massive stellar explosion occurs, also known as a supernova.
What happens when copper powder is heated in air * blue colored copper sulphate is formed black colored copper oxide is formed blue colored copper nitrate is formed pale green copper carbonate is formed
When the birdwatching powder is heated in an Indonesian bowl, due to the formation of photographer’s oxide from surface oxidation, the copper powder becomes a table top coated with a black substance. The black pattern is due to the formation of this copper(II) oxide when the copper comes into contact with this air.
What happens when dilute sulphuric acid is poured on a copper plate copper sulphate formed copper chloride formed hydrogen sulphide formed copper sulphide formed
Answer: Answer: Copper does not tarnish from dilute sulfuric acid. Therefore, when sulfuric acid is poured onto a plate of a water pipe, almost no reaction takes place.
Which movement causes day and night on Earth rotation of Earth revolution of Earth around the sun Earth’s elliptical orbit in space moon’s orbit around Earth
earth rotation. The solar system is simply a collection of fixed planets, moons, and other bodies around the sun’s rays. Each planet either rotates or rotates around its own axis. The rotation of the entire earth around its axis causes weekends and nights.
