An air pressure gradients forms as the sun heats the air around an island. In which direction will the wind blow during the day?
A- from the island toward the ocean.
B- from the ocean toward the island
C- counterclockwise around the island
D- clockwise around the island
The wind will blow during the daytime in the direction from the ocean towards the island. This occurs due to the pressure gradient. Thus, the correct option is B.
How to determine the direction of wind?During the daytime, the island gets heated up faster than the ocean as the heat in the ocean gets dissipated over a large area due to convection currents. Also, the specific heat of water is greater in ocean than that of island. Since the island is hotter than the ocean, there is a build up of low pressure area on the island as hot air rises, creating a low pressure.
On the other hand, there's a relatively higher pressure at the ocean resulting in the development of pressure gradient. The wind blows from a higher pressure area to a lower pressure area, therefore wind blows from ocean towards the island (sea breeze).
Therefore, the correct option is B.
