In the diagram below, light from the Sun strikes a beach (Z). The beach sand gains heat then warms the air that is immediately above it (X) and the sand that is immediately below it (Y).The warm air rises and is replaced by cool air (W). Which point indicates convective heat transfer?

Answer 1

In the scenario described, convective heat transfer occurs at the points where the warm air rises and is replaced by cooler air.

• X is where the warm air is located just above the beach.
• W is where the cool air moves in to replace the rising warm air.

Therefore, the correct response indicating convective heat transfer is:

W
