Or is it the Earth that’s moving? 🎙️ Core Concept (0:30–1:45) Here’s the truth: The Earth spins around itself. We call this **rotation**. It takes 24 hours to complete one full spin. As the Earth rotates, different parts face the Sun. The side facing the Sun has daylight. The other side is in darkness—nighttime! So, the Sun doesn’t move. We do! 🎙️ Recap & Thought (1:45–2:10) That’s why the Sun seems to rise and set. But really, it’s just our planet turning. 🎙️ Question for Viewer (2:10–2:30) What if the Earth stopped spinning? Would it be always day… or always night? Let’s find out in the next video!
