Why are d-block elements called transition elements?

Because the d-orbitals become split into two groups one having higher and other lower energy so the transition of electrons within these groups
continuously takes place which is also responsible for different colours of
their compounds.

Explanation:
The d-block elements are called transition metals and have valence electrons in d orbitals. The inner transition elements are those who have their last 3 shells incompletely filled. The f block elements have their last 3 shells incompletely filled.
