Cold falls so the cold created in the freezer helps to keep the fridge part cool also.

Because it would be rather tiresome for men to get ice-cubes from the bottom of the fridge, whereas cabbages are for the women to bend down and pick up :-)
More seriously, it may have something to do with the fact that cold air is denser than warmer air, so if the freezer compartment were at the bottom, all the cold air would be at the bottom, whereas being at the top, the freezer is always being cooled by evaporation of the Freon (or whatever is used nowadays) and the cold air surrounding the freezer compartment descends to the veggie part to keep it cold, but not as cold as the top bit - if that makes sense.

because its smaller, and if its placed on the bottom, then you definitely'll ought to croach right down to open it and get food out - a real inconvience. Imgaine having to open that little ingredient on the bottom of the refrigerator. The refrigerator compartment is larger, so its on the bottom for straightforward openning... not all refrigerators have the freezer compartment up correct. some have it chop up down the middle. Left is frezzer and good is frige.. And the chilly air can vacation down and cool the frige also... yet thats not continually the case (nor clarification for the freezer to be up correct), considering not all freezers are on the right as said earlier.

This has to do with air densities and at different temperatures you have different densities. Just so happens that for every form of matter, colder means heavier which means more density.
If cold air is denser then it weighs more given the same volume of hot air. So in weighing more, the cold air will fall rather than rise.
So in making a freezer with the freezing compartment at the top is just a form of efficiency. The motor has to do less work in disposing of the cold air. When it is released gravity does the rest of the job and pulls it downwards while the warmer air rises.
That's why at super markets freezers look like pools because they keep cold air in which does not rise but keeps hot air out which would not settle down low.

Cold air is denser than hot air. When the freezer chamber cools the air inside, the cold air sinks down and hot air rises up to the freezer. It allows to cool every part of the refrigerator evenly.
If freezer will be at the bottom, than the cold air will never go up, and hence the air above the freezer will never cool. This is the same reason why room heaters are placed near the ground and air conditioners are placed up.

Since cold air is denser then hot air, with the freezer at the top convection current causes the fridge part to stay cold when the freezer part is frozen. If it was backwards you would either have to have a fan or the fridge part would be too warm.

I don't think this has too much to do with physics, But you can get them with freezers on top, bottom, and side-by-side. This is a convenience for the end user, nothing more.

Not all are on top, some are to the side & some are on the bottem.

Mine is at the bottom.
