IQueryable's get converted to expression trees which then get converted to sql. It's more of a "translated" to sql rather than a "compiled" to sql. The power of IQueryable is that the expression trees can be converted to so many different kinds of expressions, and you can write your own.

IEnumerable's extensions are mostly iterators over sequences.
