Question

At the coast on a summer day, the land is hotter than the ocean. Warm air over the land rises and is replaced by cooler air, causing a sea breeze.


At night, the land cools quickly and the ocean is now warmer than the land. What will happen next?

Winds will stop blowing as the convection current ceases to flow.
The convection current will reverse direction, reversing the winds.
Winds will increase as the two convection currents overlap.
The convection current will move seaward, reversing the winds.

Answer 1

At night, when the land cools quickly and the ocean remains relatively warmer, the temperature difference causes the convection current to reverse. As the warmer air over the ocean rises, it will create an area of lower pressure over the ocean, while the cooler air over the land will sink, leading to a flow of air from the land toward the ocean. This phenomenon is known as a land breeze.

So, the correct answer is: **The convection current will reverse direction, reversing the winds.**
