Why do carbonated drinks overflow after being shaken?

Edit: someone pointed out to me that I am very wrong
Carbon is weakly bonded to the soda, making it a liquid. When you shake the soda, the carbon breaks off and spreads out into a gas, much less dense. So, the volume increases
The fizz in your soda is the gas carbon dioxide, which was dissolved in the soda the same way salt dissolved in water. Carbon dioxide isn’t very happy being dissolved in the soda, and will starts escaping as soon as you open it and release the pressure it was stored under (the pressure keeps the gas dissolved, and releasing this pressure is why soda makes a hiss when you open it). When you shake soda, all of the dissolved gas rapidly collects together into bubbles and comes out of solution. This expanding gas coming out of the liquid makes the familiar foam we all know. The same thing happens when pouring sodas.
