A Wonderleaf question
Why does wind blow?
a real page from the book
Wind blows because air moves from places where pressure is higher toward places where pressure is lower. Sun-warmed ground can lift nearby air, leaving less air pressing there, so cooler, denser air slides in. That moving air is the breeze on your face.
The memorable detail is scale: the same push and pull can make a seaside breeze, a draft around a building, or huge weather systems. Because Earth turns while air travels, winds bend into curls instead of taking the shortest path.
