Surrogate and composite primary keys

Why use composite primary key if I can use a surrogate key?
I am asking because I think it would be easier to reference one column in a where clause i.e than referencing 2 or more columns.
i.e, select .... where surrogate_key =...., rather than
where col1 = and col2 = and col3=......
