The Short Answer
The ice cream has a very rough surface and is cold. The level of dissolved carbon dioxide in the soda is a function of temperature; the colder the liquid, the less carbon dioxide it can hold. The cold temperature of the ice cream causes the soda to cool, forcing carbon dioxide to come out of solution and form bubbles. However, the carbon dioxide needs a place to start forming a bubble. The rough surface of the ice cream serves as points for the bubbles to start forming (these are known as condensation nuclei). When that many bubbles form in a liquid, it takes on a frothy, foamy texture/appearance; hence, root beer floats are foamy.
