A 6-Hour Day on Earth? 🌍 | Day 14 #shorts #earth #geology #science #trending #learning #sky #day

Imagine a day on Earth lasting only six hours. Early Earth spun much faster than it does today—and some estimates suggest its earliest days were roughly that short.

Day 14 of “365 Days to Learn the Earth”: unfamiliar skies, a faster-spinning planet, and the Moon’s role in slowing Earth’s rotation. Next: what was happening deep inside Earth?

Visuals include AI-generated scientific reconstructions. Early Earth’s exact sky color is uncertain; dust shapes the rusty daytime sky on Mars. The long-term slowing of Earth’s rotation unfolded over billions of years.
