Describe how a vein of silver forms from a solution.

A vein of silver forms from a solution by vein minerals that form in fissures in the existing rock, either thru deposition by mineral saturated hydrothermal fluids, or injection of magma and subsequent cooling.

A silver vein is formed from a solution, when that solution was hot and cooled. At that moment, the compounds in the solution (which includes silver) come out of the solution and begin to crystallize underground forming the veins of silver.

Explanation:

Vein is the name given in geology and petrology to leaf bodies of different materials, sometimes only a few millimeters thick, embedded within a rocky mass or rock. The shaft is usually formed by minerals different from those present in the embedding rock. The veins are formed when mineral constituents transported by an aqueous solution that percolates through the rock are deposited by precipitation.

A silver vein is formed from a solution, when that solution was hot and cooled. At that moment, the compounds in the solution (which includes silver) come out of the solution and begin to crystallize underground forming the veins of silver.
