The diagram below is supposed to show how a sea breeze is created by convection, but only two of the arrows are drawn correctly. select the arrows that are drawn correctly.

The arrow that are drawn correctly are the cool air current and the upper air current. In the sea breeze, warm air moves up because it is less dense that the cool air. The cool air moves down to replace the warm air. The land breeze current moves from the land to the sea while the sea breeze moves from the sea to the land. This creates a continuous flow of current at the sea level.

Hope the image of the frequency formula
