1.
conduction between Earth's surface and the atmosphere above it
2.
condensation of water vapor during the day, and evaporation of water during the night
3.
convection resulting from temperature and pressure differences above land and water
4.
greater radiation from the warmer ocean during the day and from the warmer land at night
