How do dialogue and descriptive language make a scene come alive?

They give great description to what is happening and tells the audience about what is happening and what the characters are doing. The story seems to come to life because of the detail given by the author.

The dialogue should move the story forward. It may increase suspense, show readers a trait(s) of the character(s), and/or change the situation or conflict the characters are in. Dialogue will also differentiate one character from another.

Explanation:

One of the benefits of using descriptive language is that it helps the writer to convey the meaning behind the text. By using descriptive language, the writer can describe exactly how a setting looks, how a character behaves or what action is taking place.
