Extraneous variables are variables in that could affect an experiment result and needs to be controlled. They are not the independent variable but they can occur if not well controlled in an experiment.
An extraneous variable becomes a confounding variable when it also changes with the variable that is to be studied bringing about alternative meaning to the experiment. It is automatically part of the experiment
Confounding variable should be avoided in an experiment to avoid results that are unclear.
Example of extraneous variables include environment such as temperature change, soil etc.
