Does hot air move into cold air or does cold air move into hot air?

Both. Since hot air is less dense than cold air, the hot air rises as the cold air falls (i.e. as the cold air displaces the hot air).
If you were to dye hot air & then inject it into the center of a room, you would observe the dyed hot air rising. What you may not realize is that gravity draws the (invisible) surrounding dense cold air downwards as it displaces the (visible) less dense dyed hot air.

What causes air to move along earth's surface?
The temperature changes from hot to cold or cold to hot. this makes a wind push air across the earths crust

How air masses move across the US?
In the United States air masses move across the country by air currents. These air currents are pushed by either hot or cold air masses.
How do air masses move across the US?
In the United States air masses move across the country by air currents. These air currents are pushed by either hot or cold air masses.
Why is hot air heavier than cold air?
Heat itself is a form of energy. This gives the air molecules more kinetic energy. Thus, with more kinetic energy, the air molecules move a lot more. Adversely, in cold air, there is less energy, thus the air molecules move less slowly. This is what gives hot air more volume than cold air. (Yeah I know I used more commas than I should've.)
