Here's a breakdown:
* Fighting: Fighting-type moves are super effective against Rock-types.
* Ground: Ground-type moves are super effective against Rock-types.
* Steel: Steel-type moves are super effective against Rock-types.
* Water: Water-type moves are super effective against Rock-types.
* Grass: Grass-type moves are super effective against Rock-types.
Keep in mind that some Pokemon might have multiple type advantages, making them even more potent against Rock-types. For example, a Garchomp (Dragon/Ground) benefits from both Ground and Dragon-type advantages against Rock.
