The silver nitrate is in solution and the metallic copper will dissolve to form copper nitrate; as it does, it will precipitate the silver in solution as metallic silver.
This is a Displacement reaction as copper is more active than Silver(referring to activity series),copper displaces silver from its nitrate solution.
