Extraneous variables are unaccounted for variables that CAN POTENTIALLY affect the results (i.e. YOU DO NOT KNOW IF THE EV HAS AFFECTED THEM OR NOT)

Confounding variables are unaccounted for variables THAT DO affect the results (i.e. YOU KNOW FOR SURE THAT THEY HAVE AFFECTED THE RESULTS, THEN IT IS A CONFOUNDING VARIABLE)

If you know the E.V. has definitely affected the experiment, then it is a confounding variable.
It just depends on whether you know it affects the experiment or not.
