The ultimate source of energy for plants is the sun. Sunlight is one of the main components of photosynthesis.
In order to form another type of rocks that are to be deposited in some other environment, the source rock must undergo the process of weathering and erosion. Weathering leads to the breakdown of rocks and erosion leads to the transportation of the broken fragments and sediments.

Explanation:
Electroplating involves the coating of one metal on another metal. It is an electrochemical process. The positive electrode is the coating metal while the negative electrode is the metal on which the coating is to be performed.
Since copper is to be coated on an iron nail. A copper plate is made the positive electrode while the iron nail should be the negative electrode.
The electrolyte used in the process should be a copper salt e.g CuSO4 solution.
As electrolysis progresses, the copper electrode(positive electrode or anode) gradually wears away due to the fact that the copper ions are going into the solution and are being deposited on the iron nail.
