How do waves form in the sea?
Stand at the ocean's edge and you'll see them marching in — wave after wave after wave, rolling toward shore like they've been doing it forever. Where do they come from? What makes the sea ripple and rise and crash? The answer starts far from the water, up in the air above you.
Wind is the wave-maker. When wind blows across flat water, it drags on the surface like fingers brushing across a tablecloth. That friction tugs the water upward into tiny ripples. The stronger the wind, the bigger the tug. The longer the wind blows, the more those ripples grow.
