I'm a bit confused about the difference between a clog and a jam. Can you help?

A clog is a blockage in a pipe or drain that prevents water from flowing through it, while a jam is when something stops up a pipe or drain completely. Clogs are usually caused by grease, hair, soap scum, or other debris, while jams can be caused by tree roots, food particles, or even a buildup of air bubbles. Clogs can typically be cleared with a plunger, but jams require professional help to fix.
