💡 From a breeze to a monsoon
Wind is simply air moving from high pressure to low pressure — and those pressure differences come from the Sun heating the Earth unevenly, from a hillside breeze to planet-wide winds.
How does uneven heating cause winds?
- Wind is the movement of air from a region of high pressure to a region of low pressure.
- These pressure differences are mainly caused by the uneven heating of the Earth’s surface by the Sun.
- Uneven heating of land and water also drives land and sea breezes; the same idea explains winds and ocean currents at every scale.
