The second difference is in the coverstock--the outside material of the bowling ball. They range from plastic at the low end, through hard rubber (far more popular in the past), to exotic reactive resin compounds.

All of these differences serve to provide a wide variety in the way bowling balls react to various bowling styles and lane conditions.
