Answer:
A heating up the Earth's surface unevenly
Explanation:
Wind comes from the sun heating up the earth's surface unevenly. This causes air masses to have different temperatures. Differences in temperature causes the density of the air masses on the earth surface to differ.
- This leads to the movement of air from regions of high density to places with low density.
- Therefore, convection cells are then set up by the implication of this.
- The movement of the air masses causes wind.
