Participles in English are often used as adjectives (“the living dead”, “a baked ham”), but they are more commonly used as they are here, with to be to create the continuous tense of verbs.
“He sits” — he typically sits; he characteristically sits; he is just now assuming a seated position.
“He is sitting” — at this moment, he is in a seated position.
(To be clear, “progressive” or “continuous“ is not a tense; it is an aspect of a tense, so there is past continuous, present continuous, and so on.)
