"Above the sea, warm air rises, cools, and sinks."
That describes convection—heat transfer by the bulk movement of a fluid (air here). The others are radiation (sun heating the ground), evaporation/evaporative cooling or conduction (pouring water on her face), and conduction/radiation (feet heating from hot sand).
