Air or helium is a gas that is contained in a latex envelope. Since the balloon is a finite space, when you sit on it you strain the latex beyond it's capabilities. Just like a seam in your clothes, too much strain will open the material. In latex, the thing pops because the pressure outside is greater than the pressure inside. The gas has to go somewhere!

The answer is fairly simple, while some believe that a balloon bursts when near hot air because the balloon simple melts, it actually has to do with the pressure inside the balloon. When near hot air, the air inside the balloon expands slightly, causing a change in pressure, and causing the balloon to burst.
