How was gold formed within the earth?
Solution
Hint : Gold has long been related to a divine sphere, both in pre-Christian and in Christianity. The shine of gold, its indestructible nature, its malleability and its relative scarcity made it a perfect material to embody divine qualities, but also expressions of human veneration of the divine.
Complete Step By Step Answer:
Scientists believe all the gold on Earth formed in supernovae and star collisions that occurred before the 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 due to asteroid bombardment
During the formation of Earth, molten iron sank to its center to form the core. This took with it the overwhelming majority of the planet's precious metals - like gold and platinum. In fact, there are enough precious metals within the core to hide the whole surface of Earth with a four meter thick layer.
The removal of gold to the core should leave the outer portion of Earth deprived of bling. However, precious metals are tens to thousands of times more abundant in Earth's silicate mantle than anticipated. It's previously been argued that this serendipitous over abundance results from a cataclysmic meteorite shower that hit Earth after the core formed. The complete load of meteorite gold was thus added to the mantle alone and not lost to the deep interior.
Note :
Today, much of the world's gold comes from other nations round the world. These include China, Russia, Australia, South Africa, and various countries in South America. At this point, about 3,000 plenty of gold is mined annually, which represents approximately 5.4 cubic meters.
