Where Does the Copper Used for Wiring and Plumbing Come

Question

Where does the copper used for wiring and plumbing come from?  
A) Most copper is found in ocean sediments.
B) Most copper is mined from the ground.
C) Most copper is found along riverbanks.
D) All copper is mined from the surface.
E) All copper is manufactured synthetically in factories.

Accepted Answer

Most copper used for wiring and plumbing comes from mines in the ground, as the ore is typically found in large deposits underground. While copper can also be found along riverbanks, it is generally a smaller source and not sufficient for industrial purposes. Copper is not typically found in significant amounts in ocean sediments, and while it can be recycled and manufactured synthetically, this process is not typically used for industrial scale copper production.
