Sky

The sky is the vast expanse above Earth's surface, appearing as a broad canopy of atmosphere. During the day, it looks blue due to sunlight scattering off particles in the air. When the sun sets, the sky changes colors—reds and oranges—in a spectacle called sunset. At night, the sky reveals stars, planets, and the moon. The sky's appearance and phenomena are influenced by Earth's atmosphere, weather, and celestial events, providing a dynamic backdrop to our daily environment. It’s a crucial element for weather patterns, climate, and navigation, connecting us to the broader universe.
