Planes use flaps to land and to take off. So why do they retract them while they are on the ground, ie why not just leave them deployed?

Less possibility of foreign object damage from ground based things getting into the wings/flap mechanisms.

The settings for the flaps are different for takeoff as well as landing, so some adjustment is going to have to take place anyway.
