🌞 Polar day is when the sun doesn't go to bed at all! It stays up in the sky for many days or even months! This happens in places very far north or south, like where Santa Claus lives! 🎅
🌚 Polar night is the opposite—the sun takes a long nap, and it's dark for many days or months. Brrr, that sounds cold! ❄️
This happens because the Earth tilts like a spinning top, and some places get extra sun or extra darkness.
🌞 Polar day (or midnight sun) happens near the North and South Poles. For weeks or months, the sun never sets—it just circles the sky! This occurs in summer because the Earth's axis is tilted toward the sun. 🌍↗️
🌚 Polar night is the opposite: in winter, the Earth tilts away, and the sun stays below the horizon for weeks. It’s dark all day! Some places use lamps to mimic sunlight. 💡
Why? The Earth spins at a tilt (23.5°), so polar regions get extreme sunlight or darkness.
🌞 Polar day occurs in Arctic/Antarctic regions during their summer. The sun remains visible for 24+ hours due to the Earth’s 23.5° axial tilt. At the poles, the sun circles the horizon without setting! 🔄
🌚 Polar night happens in winter when the sun stays below the horizon for months. Temperatures plummet, and artificial light is essential. Some animals hibernate; others, like Arctic foxes, adapt to the dark. 🦊
Science: Earth’s tilt causes seasons. Near the poles, the tilt creates extreme daylight/darkness cycles. The Arctic Circle (66.5°N) marks where polar day/night begin.
