- Ultraviolet light
- Solar flares
- Meteorites
- Dead animals
The Answer:
And, the answer for the the question is :
Explanation:
Researchers from the University of Bristol revealed in 2011 that gold and the rest of the precious metals found on Earth likely came as a result of meteor bombardments approximately 200 million years after the Earth was formed. This conclusion was reached after the researchers analyzed some of the oldest rocks known to exist on Earth. They also predicted that there are sufficient precious metals in the core of the Earth to cover the surface of the planet with a layer that is 4 meters (13 feet) thick.
Earth’s precious metals, such as gold, silver, and platinum, have long been the subject of fascination and desire. But where did these valuable elements come from? The answer may surprise you – many scientists believe that Earth’s precious metals came from meteorites.
Meteorites are rocks that have fallen to Earth from space. They are made up of a variety of elements and minerals, including many of the precious metals that we value today. Scientists believe that these metals were formed in the hearts of stars, and were then expelled into space during supernova explosions. Over time, these metals were incorporated into asteroids and other celestial bodies, which eventually collided with Earth.
While most of Earth’s precious metals are believed to have come from meteorites, some may have also been produced by volcanic activity and other natural processes. However, the amount of precious metals that can be produced through these processes is relatively small compared to the amount that can be found in meteorites.
The discovery of Earth’s precious metals has played an important role in the development of human civilization. These metals were valued for their beauty and rarity, and were used to create jewelry, coins, and other decorative objects. They were also used in a variety of industrial applications, such as electronics and medicine.
the demand for Earth’s precious metals continues to be strong, and they remain highly valued commodities in the global economy. However, the extraction and use of these metals can also have negative environmental and social impacts, such as pollution and exploitation of workers. As such, it is important to carefully consider the costs and benefits of using Earth’s precious metals, and to work towards more sustainable and responsible practices.
Earth’s precious metals are believed to have come from meteorites, which contained these valuable elements that were formed in the hearts of stars. The discovery of these metals has played an important role in human history, but their extraction and use can also have negative impacts. As we continue to value and use Earth’s precious metals, it is important to consider the ethical and environmental implications of their extraction and use.
