Question

The drawing shows a cross section where the land meets the sea. The section covered is 5 kilometers. On a hot day, in which direction, indicated by four arrows, is the wind most likely to blow?

• A. D
• B. A
• C. B
• D. C

Answer 1

The Correct Option is A

The direction in which wind is likely to blow near the sea is influenced by the differential heating of land and water. During a hot day, the land heats up faster than the sea due to its lower specific heat capacity compared to water. This temperature difference creates a pressure difference. Warm air over the land rises, creating a low-pressure area. Cooler air from the sea, which is at higher pressure, moves in to replace the rising warm air, resulting in a sea breeze blowing towards the land.

Referring to the diagram, the correct arrow indicating the wind direction on a hot day would be the one pointing from the sea towards the land. As per the options provided:

Option	Direction Description
A	Inland from the sea
B	Parallel to the shoreline
C	From the land towards the sea
D	From the sea towards the land

Based on the reasoning above, the correct choice is Option D.
