Why does this change?

Irregular
Doesn't follow a predictable pattern in at least one tense — these forms are worth memorizing individually rather than deriving from a rule.
Stem-changing
The vowel in the stem changes in most forms (e.g. e→ie, o→ue) — but the endings themselves stay completely regular.
  • e→ie in the present tense (except nosotros)
  • gerund: advirtiendo

Conjugates like convertir/sentir: e→ie in most of the present, e→i in the 3rd-person preterite and gerund (advirtió, advirtiendo).
