The term "more erose" is typically used in geology to describe a surface that is more uneven or irregular than others. Instead of using the term "more erose," one could use a variety of synonyms such as rugged, jagged, uneven, bumpy, or rough. All of these terms describe a surface that is not smooth or regular, but rather has irregularities or bumps on it. Depending on the context, one might choose a synonym based on the degree of unevenness or the specific appearance of the surface. Regardless of which synonym is chosen, they all convey the same basic idea of a surface that is rougher or more uneven than others.
