Why Do We Have Day and Night? The Science Behind the Cycle Have you ever wondered why the world doesn’t just stay sunny all the time? Or why, while you’re tucked into bed in London, someone in Sydney is just starting their lunch break?

Imagine a globe with a rod running through its center from top to bottom. That rod represents Earth’s axis, an imaginary line around which our planet rotates. Every 24 hours, Earth completes one full spin—or rotation—on this axis. why do we get day and night

If Earth spun perfectly upright, day and night would each last exactly 12 hours everywhere, all year long. But our planet is tilted on its axis by about 23.5 degrees. That tilt causes the Sun to spend more or less time above the horizon depending on the season and your location on Earth. Why Do We Have Day and Night

| What causes day and night? | Earth’s rotation on its axis once every 24 hours. | | :--- | :--- | | What is day? | The side of Earth facing the Sun. | | What is night? | The side of Earth facing away from the Sun (in its own shadow). | | Why aren’t days always 12 hours long? | Earth’s axis is tilted, causing seasonal variations in daylight. | Imagine a globe with a rod running through

Imagine the Earth as a spinning top. It takes our planet roughly 24 hours to complete one full spin (a rotation).

The Earth spins on an imaginary line called an , which runs through the North and South Poles. Day and Night Explained in One Minute

It’s easy to take the sunrise and sunset for granted, but the daily rhythm of our world is caused by a massive, never-ending celestial dance.
