The sun powers the water cycle.
Clouds form through the process of condensation.
Humidity
Humidity is the amount of water
vapor in the air.
It feels hotter than the actual
temperature when it’s humid
because the body can’t sweat
properly.
It would be very humid in areas
closer to the equator and coastal
regions.
As air gets warmer,
the amount of
water vapor that
the air can hold
increases.
