What does a chasm have to do with gulf?

A chasm and a gulf both refer to deep, steep-sided openings or depressions in the Earth's surface. While a chasm is typically a deep fissure or ravine, often formed by erosion or geological activity, a gulf usually refers to a large sea or ocean inlet that is partially surrounded by land. Both terms convey a sense of depth and separation, but they apply to different geographical features. Essentially, they are related in that they describe significant forms of landscape created by natural processes.
