Question

How can a convection current affect the temperature and humidity at a beach

Answer 1

Convection is one of the three main types of heat transfer. Unlike the other two, convection can only happen in fluids. This includes liquids and gases and is because the molecules have to be free to move.

Heat energy can transfer by convection when there is a significant difference in temperature between two parts of a fluid. When this temperature difference exists, hot fluids rise and cold fluids sink, and then currents, or movements, are created in the fluid.

On a hot sandy beach the sudden lovely cool breeze is a result of convection.
