<u>Answer:</u>
Heat moves from the land to the air through the process of "conduction".
<u>Explanation:</u>
When the two things come in contact with one another at different temperatures or basically when heat flows from the warmer to the colder region or phase until both reach at the same temperature is understood as "conduction". Conduction is a physical process which occur by collision of the microscopically colliding particles like molecules, atoms and electrons on the movement of heat through a substance.
While convection take place by the movement of heated objects and it isn't the process influencing air and water temperature difference. The examples of conduction are like a radiator, a heating pad, sand can conduct heat etc.
The defining characteristic of the intertidal zone is that it is submerged with water during high tide and exposed to the air during low tide. The zone can take many forms, from sandy beaches to rocky cliffs. It is common for the intertidal zone to change frequently, since it is constantly battered by crashing waves.
