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 appear as deposits, commonly referred to as veins or veins, which break down as they move. It can also be distributed in crusty soils. Most vein deposits occur when heated fluids flow through gold-bearing rock, picking up gold and transporting it to new locations in the earth’s crust.
Does the earth naturally produce gold
In its natural form, it is believed to be found deep in the layers of the earth, where it is held by water, molten lava, as well as volcanoes, eruptions, and earthquakes. Geologists have definitely found gold in rocks 4.5 billion years old.

Does gold come from space
Unlike other metals, this version of the Earth’s golden crust comes from space. Stars are mostly made up of helium and hydrogen, which light bulbs provide. Nuclear fusion releases energy in the core of a star. As the star’s entire life comes to an end, a massive stellar explosion occurs, which is thought to be 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 truck driver powder is heated in the body of the Chinese online store, the surface of the copper powder is coated with a black substance due to the formation of truck driver oxide by surface oxidation. The black pigment is formed with this copper oxide in the form of a copper mineral that comes into contact with human 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 react with dilute sulfuric acid. Thus, when exposed to sulfuric acid on the copper plate, no reaction occurs.
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 not a stationary cluster of planets, moons, but also other bodies around the sun. Each planet twists or twists everything around its axis. The rotation of the corresponding earth on its axis causes day and night affairs.
