Copper is primarily formed through hydrothermal processes, where hot fluids containing dissolved copper minerals flow through cracks in rocks and deposit the copper as it cools. Another common way copper forms is through weathering and erosion of copper-bearing rocks, releasing copper atoms that can then be washed into sedimentary deposits.

Why is there so much copper in Arizona?
The initial source for copper in Arizona were igneous intrusions into native host rock. The copper veins were eventually exposed through erosion at the surface. Copper then leached back into the ground and recrystallized in the form of copper minerals in what is called a supergene enrichment zone. The igneous intrusions were due to a long period of magmatism from the middle of the Mesozoic to the early Cenozoic era.
Is copper pure form?
No, copper is typically not found in its pure form in nature. It is usually found in combination with other elements in ores, which must be processed to extract the pure copper metal.
Can copper and sulfur combine into a compound?
Yes, copper and sulfur can combine to form a compound called copper sulfide. This compound can exist in different forms, such as copper (I) sulfide and copper (II) sulfide, depending on the oxidation state of copper.
In what form is copper found in nature?
Copper is commonly found in nature in the form of sulfide ores, such as chalcopyrite, bornite, and chalcocite. It can also be found in the form of oxides, carbonates, and native copper, which occurs as pure copper metal in its natural state.
Does copper oxide form precipitate in water?
Yes, copper oxide can form a precipitate in water by reacting with certain substances. It typically occurs when copper ions from copper compounds react with hydroxide ions to form insoluble copper hydroxide, which appears as a precipitate. This process can be influenced by factors such as pH, concentration, and temperature.
What do the relative geologic time and absolute geologic time combine to form?
The geologic time scale.
What caused the copper to have greenish spots?
The greenish spots on copper are caused by a chemical reaction known as oxidation. When copper is exposed to air and moisture, a green patina called copper carbonate forms on the surface, creating the greenish spots.
What makes copper rust?
Copper does not rust like iron, but it can develop a greenish layer called patina when exposed to air and moisture. This patina is primarily composed of copper compounds such as copper carbonate and copper hydroxide, which form a protective layer on the surface of the copper, preventing further corrosion.
How does black copper oxide form?
CuCO3 + Heat --> CuO + O2 Green Copper Carbonate when heated will form Copper Oxide and Oxygen
How does copper react with other chemicals?
it starts to stink and then has a massive fart and pops out a bubble

What is the Meaning of blister in blister copper?
In the context of blister copper, "blister" refers to the appearance of the copper after it is extracted and processed. Blister copper contains gas bubbles that form during the smelting process, giving it a blistered or bubbly appearance.
What do copper and oxygen form when chemically united?
Copper and oxygen form copper(II) oxide (CuO) when chemically united.
When copper and oxygen chemically unite the form?
Copper oxide
Does copper with oxygen?
Yes, copper reacts with oxygen to form copper oxide.
What are some of the reactions cooper has with other elements?
Copper can react with other elements, such as oxygen, sulfur, and chloride to form an ore, copper oxide (CuO); tarnish, copper sulfide (CuS); and the salt, copper chloride (CuCl2) used in many chemistry labs.
What geologic feature may form at a divergent bound?
A rift valley
