Abyss is to chasm as fissure is to?

Ah, what a lovely question! Just like how an abyss is a deep, vast space, a chasm is also a deep opening in the earth. Similarly, a fissure is like a narrow opening or crack, so the relationship between abyss and chasm is akin to fissure and crevice. Remember, each Word paints a beautiful picture in our minds!
