Watching a sunset at the beach is an amazing experience! Every night, as the sun sets, the sky lights up with a glorious array of colors that fill the horizon. The red coloring in a sunset comes from a phenomenon called Rayleigh scattering. It happens when sunlight passes through dust and other particles in the Earth's atmosphere, which refracts and reflects, creating a vibrant red hue. When you watch the sun dip below the horizon and you see the sky turn all shades of pink, orange, and red—it’s truly a breathtaking view!
