07.09.2019How is gold formed geologically? One hypothesis is that many gold deposits, especially those found in volcanic and sedimentary rocks, is formed from circulating ground waters driven by heat from magma, intruded into the earth's crust within about 3 to 5 miles off the surface.

01.02.2022How is gold formed? There are two main theories about how gold is originally formed, both involving stars. One involves the explosion of supernova stars and the resulting nuclear fusion creating atoms of gold, and the other, the collision of neutron stars that results in a gamma-ray burst, one of the most powerful explosions possible.

Does the moon have geological activity? Although there is a small amount of geological activity on the Moon, it is largely dead geologically (the energy associated with the Earth's seismic activity is about 10^14 times larger than that of the Moon). Most Lunar seismic activity appears to be triggered by tidal forces induced in the Moon by the Earth.

The water follows cracks and folds in the land as it flows downhill. Small streams meet and join together, growing larger and larger until the flow can be called a river. On its way down, the water shapes the landscape by wearing away rock and carving out a network of valleys. Reaching lower ground, the river widens and takes a winding route.

Secondary gold actually comes from primary gold and is often found in streams, rivers, waterways, and creek beds. This secondary gold, called placer gold, is a result of millions of years of erosion of primary gold. Wind, water, and temperature changes can flush minerals from rock formations, in the form of gold dust, fine grains, and even nuggets.
