"Above the sea, warm air rises, cools, and sinks."
That's convection — heat transfer by the bulk movement of a fluid (air or water). The others are different processes: the sun heating the ground is mainly radiation, Amaya pouring water uses evaporation/evaporative cooling (and some conduction), and Stephan's feet getting hot on sand is conduction.
