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

The point that indicates convective heat transfer is W.

Convection involves the movement of warmer air rising and being replaced by cooler air. In this scenario, warm air above the beach (X) rises and is replaced by cooler air (W). Thus, W is the point where convective heat transfer occurs.
