🌞 The Earth is like a big spinning ball! When your side of the Earth faces the Sun, it's daytime 🌞. When it turns away, it's nighttime 🌜.
Imagine spinning around with a flashlight—when the light shines on you, it's 'day,' and when it doesn't, it's 'night'!
🌍 Day and night happen because the Earth rotates (spins) like a top! It takes about 24 hours to spin all the way around.
When your part of the Earth faces the Sun, it's daytime ☀️. When it turns away, the Sun's light can't reach you, so it's nighttime 🌙.
The Earth's rotation also makes the Sun appear to rise and set—but really, it's us moving!
🌎 Day and night are caused by Earth's rotation—its spinning motion around its axis (an imaginary line through the North and South Poles). One full rotation takes 23 hours, 56 minutes, and 4 seconds (roughly 24 hours).
When your location faces the Sun, sunlight reaches you, creating daytime. As Earth rotates, your location moves into darkness, causing night.
This rotation also creates time zones—different parts of Earth experience day/night at different times.
Fun fact: Earth's tilt (23.5°) causes seasons, but rotation causes day/night!
