I'd say Parokki is right, it's not a style, it's a word.
It's like how in Japan Cowboy bebop is drawn differently from naruto yet they fall under the same umbrella of being manga/anime, similarly to how simpsons and Boondocks fall under the umbrella of cartoon.
So basically (to borrow a little bit of what Soriku said):
Manga - Comics
Anime - Cartoon Shows.
A good example would be like the simpsons comic and the simpsons show, a better example would be super hero cartoons, because some of them run story lines that appeared in the comics, which is how manga/anime work (most of the time).
