SSSSS [86.1K]

The correct flowchart is energy - > atmosphere - > air pressure - > convection - > global winds. This is a very simple process as explained.

<h3><u>Explanation:</u></h3>

The energy from the sun actually heats up the land surface and the water surface of the earth. As the land gets heated up, the layer of atmosphere that is adjacent to the land and water also gets heated up. This leads to the decrease of air density as the heat causes expansion of gases. With decrease in air density, the air pressure also drops and the air from the cooler layer of atmosphere above comes to fill up the space and this heated air goes up. This causes the convection current to get set up. This causes the global winds and different oceanic currents to flow all over the earth throughout the year.
