The Earth rotates alongside an imaginary line that runs from North Pole to South Pole. It’s known as the axis, and this rotation is what provides us day and night time.

However, the axis tilts at 23.5 levels, as NASA explains. That positions one hemisphere of the planet to get extra daylight than the different for half of the yr’s orbit round the solar. This discrepancy in daylight is what triggers the seasons.

The impact is at its most in late June and late December. Those are the solstices, and so they have the most excessive variations between day and night time, particularly close to the poles. (That’s why it stays darkish for therefore lengthy every day throughout the winter in locations similar to Scandinavia and Alaska.)

This bending of sunshine rays “causes the sun to appear above the horizon when the actual position of the sun is below the horizon.” The day is a bit longer at greater latitudes than at the equator as a result of it takes the solar longer to rise and set the nearer you get to the poles.

We acquired that really equal day/night time cut up just a few days earlier than the official spring equinox. That’s called the equilux.
