My teacher has asked me to identify and explain how Shakespeare creates atmosphere in Act 1, Scene i.

I think he creates atmosphere by making the readers to think what will happen to Prince Hamlet and the ghost? I'm not really sure how to answer this question...

You're basically right. The dark, winter night and the presence of the ghost certainly creates an ominous atmosphere.

Ok, so do I blab about how the guards were frightened by the ghost, then when Marcellus swing his partisan towards the ghost to stop it from leaving, the setting itself and how Horatio is questioning why was the ghost there?
NO, you're showing how Shakespeare creates atmosphere like by the weather.
