Review the examples below. Which would be considered an example of convection.

Question

a
boiling water on a hot stove
b
sunlight warming your face
c
a glass of water on a counter at room temperature
d
sea breeze moving from the warm beach to the ocean

Answer 1

The correct answer is (d) sea breeze moving from the warm beach to the ocean. Convection is the transfer of heat through the movement of fluids (liquids or gases) from one area to another. In this example, the warm air over the beach rises, creating a lower pressure area, and cooler air over the ocean moves in to replace it, creating a sea breeze. This movement of air from one place to another represents a convection current.
