The correct answer is: heavy eroded particles settle out of moving water. Placer deposits are formed when heavy eroded particles settle out of moving water. Placer deposits accumulate naturally heavy, valuable minerals, which are formed by the gravitational effect during the sedimentary processes. As a result, these minerals are concentrated in residual, the beach and the sequence of the deposits, forming ore deposits.
