No... a land breeze is sort of the opposite of a sea breeze... as sun shines on a coast line the land, as mentioned before, warms more quickly than the surrounding water (specific heat, i think). Warm air rises. Result is a local low pressure region, with high pressure existing over the water. Wind flows from high to low and the result is a sea breeze. At night land cools faster than water, so the result is warm water heating an air mass, causing convection and assosciated low pressure region. Wind blows offshore and the result is a land breeze....
Advection fog is less of a phenomenon and more of a weather system (kinda sorta, you'll see what I'm getting at). With advection fog you need a warm air mass to exist over a cold body of water (kind of like in the beginning of a land breeze), but prevailing winds have to advect (push) it over a land mass. In addition, the airmass has to become saturated as it is moved over the cold water, then come ashore as fog, hence the term advection. In Fl, some sort of land or seabreeze occurs probably 180 days of the year, but I've never witnessed advection fog, due to the lack of a near-shore cold current. During periods of upwelling the case may be different.
We see radiation fog nightly in forested areas though... espescially in the fall/winter.
