How did the battle of the Monitor and the Virginia change naval warfare?

It was our first naval battle that used many weapons that changed how we use naval ships and weapons. It was a battle between iron clad ships. Up to then, war ships were wooden with copper plating to protect it from damage by shells. These ships were covered with iron and many shells would bounce off their plating.
With the introduction of steam powered ironclad warships, the days of the wooden sailing ship were numbered. Tactics and, eventually, strategies changed to reflect the vessels' abilities to fire and maneuver.
