I know it is a silly question- but I am having a debate with my friend- I swear my 4th grade teacher told me this- however I attended the 4th grade many years ago...I couldn't find anything in Wikipedia...HELP!

NO, but the wrinkles are where advanced intelligence lies.
The brain is composed of neurons and neurons are to the brain like steel beams are to a skyscraper. When you learn something you make new connections of neurons. This is how memory is stored.
Different areas of the brain controls different functions. The frontal cortex is where we put our memories; the cortex is where the basic reflux functions of life start etc. The thing that we think of as intelligence happens in the convolutions of the brain; the wrinkles; the more wrinkles a brain has the more intelligent an animal is.
Humans are over 95% identical to chimpanzees and apes; according to our DNA. The few differences are what makes us humans and not apes. One of those differences determines the wrinkles in the brain. Humans have more brain wrinkles than apes, and apes have more wrinkles than dogs and more than birds etc.
So the new thing you learned is in a combination of neurons, but those neurons are in the wrinkles. When you learn something new you don't get a wrinkle in your brain. The wrinkles in your brain determine the limit of things that you can learn and how intelligent you can get.
According to Wikipedia: http://en.wikipedia.org/wiki/Human_brain#Anatomy
“The bulbous cerebral cortex is composed of convoluted grey matter”
The convolutions are the wrinkles and the grey matter is what we use to think. The cells that form the grey matter and the rest of the brain are neurons. When you learn you make new neuron connections.

My brain smiles when I learn something. And, yeah, I guess smiling can cause wrinkles.

no.
there is no macroscopically visible alteration in its structure.
there ARE a lot of chemical and structural changes, but these occur at a microscopic level.

No, the folds are already there, you're just making more stuff in the middle work better.
