Hi there! Let's talk about something cool about the sun and the Earth. The Earth is like a big ball that spins around, and the sun shines light on it.
At the very top and bottom of the Earth, called the North Pole and the South Pole, something special happens. Sometimes, the sun doesn’t come up at all for days or even months! That means it stays dark for a long time. This is called the 'polar night.'
Here’s why: The Earth is tilted a little bit as it spins. When it’s winter at one pole, that pole is tilted away from the sun. So the sun doesn’t shine there, and it stays dark. When it is summer, the pole is tilted towards the sun, and the sun stays up all day and night!
This is why people who live at the poles have very long days in the summer and very long nights in the winter.
Isn’t that neat? The sun’s light depends on how the Earth is tilted and where you are on Earth.
