Usually referring a specific movement of water, "to cascade" refers to the action of large quantities of liquid pouring downward. For example, imagine a waterfall. The movement of so much water pouring downwards over a cliff is called "cascading." "Cascading" can be used to describe nouns that reflect this action. It's also used in other situations to describe things that fall or hang in large quantities. Ex: The beauty of that cascading waterfall! Ex: The plastic balls in the ball pit cascaded down the moment I jumped in.
