What role does the chorus play in Medea?

The chorus in Medea, as opposed to the one in Oedipus, offers a lot more insight to situations and also it asks a lot of questions. an example of this s on page 44 where the chorus says "Whom will you turn to? Where will you turn? What country, what stranger, what home for a haven? Who will receive you?". They seem to be a lot more caring about Medea's situation as opposed to the chorus in Oedipus where they didn't show much emotion. Overall, the chorus adds a lot of curiosily to the minds of the reader.
